In my project I'm getting the error
```
In file included from lib/Discovery/Discovery.cpp:2:
C:/Users/David/.platformio/packages/framework-arduinoespressif32/libraries/AsyncUDP/src/AsyncUDP.h:47:1: error: expected class-name before '{' token
```
Adding a reference to Stream.h fixes it.
* Added dual antenna for WiFi (based on the ESP32-WROOM-DA module)
* Fixed build error
* Fixed indentation and renamed function to setDualAntennaConfig
* Added the RX and TX selection modes as configuration
* Mode code optimization
Summary
Touch Sensor refactoring to be based on IDF 4.4.
Adds support to ESP32S2 and future ESP32S3.
Adds some new APIs:
For all chips:
void touchAttachInterruptArg(uint8_t pin, void (*userFunc)(void*), void *arg, uint32_t threshold);
This function allows the user to add and pass a void* parameter to the ISR user callback.
void touchDetachInterrupt(uint8_t pin);
This function detaches ISR call back for the touch pad pin.
Only ESP32 chip
void touchInterruptSetThresholdDirection(bool mustbeLower);
This function allows the user to set if the ISR callback will be activated when the touch sensor readings are lower or higher than the threshold defined. See example TouchButton.ino.
Only ESP32-S2 and ESP32-S3 chips
bool touchInterruptGetLastStatus(uint8_t pin);
This function reports if the touch pad pin is touched or untouched. It can be used with ISR to identify when it is touched and untouched (released). See example TouchButtonV2.ino.
Impact
None. ll original APIs and examples now run on ESP32 and ESP32-S2.

I found with wireshark a possibility to trigger the crash on demand is:
nslookup 3.1o1osr0092ons87rp375p1pq8q066o8p56or1sqsps6rs17r4384q9748qr1r52.699p1r741q737393648s29917o45p16q50rn517rnsp73pp68p1q259s92693qp.s607408539s0p06p7559os0899866344r7qq7rpns960o9576q65.r5n94r5so9784pq1.i.03.s.sophosxl.net
The problem was that QNameLength is a signed byte and therefore its not possible to count up to 255. Additionally we need 256 bytes for the QName string to accommodate for the zero termination.
With LittleFS the `fs.exists(path)` returns true also on folders. A `isDirectory()` call is required to set _isFile to false on directories.
This enables serving all files from a folder like : `server->serveStatic("/", LittleFS, "/", cacheHeader.c_str());
File f = fs.open(path);
_isFile = (f && (! f.isDirectory()));
Reliability fix for autoReconnect when assoc_fail, autoReconnect did not work before for these failures.
Changes behavior of WIFI_REASON_ASSOC_FAIL event when autoReconnect is set, removes WIFI_REASON_ASSOC_FAIL/WL_CONNECT_FAILED so retry waitforconnectresult loop stays active for the retry, was not working before.
* change parameter to signed int
As of wrong paramater, the following problem existed, that will be fixed now with this change.

* Change parameter and variable to int

* Revert "Examples update, add a note for configTime() that only one ntp server is supported by lwip",

Summary
This PR is refactoring of SigmaDelta HAL in order to use IDF instead of current Register manipulation approach.
Impact
Change in API:
uint32_t sigmaDeltaSetup(uint8_t channel, uint32_t freq);
changed to -->
uint32_t sigmaDeltaSetup(uint8_t pin, uint8_t channel, uint32_t freq);
void sigmaDeltaAttachPin(uint8_t pin); removed, no longer needed. Pin is attached in sigmaDeltaSetup()
Summary
RMT HAL refactoring based on IDF.
Impact
Improves RMT by adding IDF v4.4 support.
Receiving RMT can handle any size of data.
rmtInit() has a new parameter - RxBufferSize - to hold any number of data when receiving RMT.
rmtWrite() has a new parameter - wait_tx_done - to block writing until sending all data.

23 Braille Display Page (0x41)
Braille display allow visually impaired computer users to read out text using raised pins. The pins are electro-mechanically
activated. These devices also have support for controls that help navigate the computer screen. Typically, braille displays
interface with software known as a screen reader in order to perform this navigation.
## Summary
Arduino ```setup()``` and ```loop()``` run under a Task with a fixed Stack size of 8KB.
Users may want to change this size.
This PR adds this possibility by just adding a line of code, as for example:
``` dart
ESP_LOOP_TASK_STACK_SIZE(16384);
void setup() {
}
void loop() {
}
```
## Impact
None. It adds a new functionality to ESP32 Arduino.
If ```ESP_LOOP_TASK_STACK_SIZE(newSize);``` is not declared/used, it will compile the sketch with the default stack size of 8KB.

Thanks @igrr for the suggestion!
* Refactoring function headers
Changing the header so the main TwoWire::requestFrom() definition uses a `size_t` instead of a `uint8_t`, removing the 255 bytes limit on I2C requests.

* using ksz8081 only from ESP-IDF 4.4 onwards
The previous assertion only considerate the existance of ESP-IDF 4.3, but with the ESP-IDF 4.3.1 release this assertion would generate errors. Now only includes from ESP-IDF 4.4 onwards.

Current implementation clears _headers when request was sent. If the
user added custom request headers, they will be lost and the redirected
request will not contain them. This commit changes the scope of cleanup
so that the headers survive redirects but don't survive connection
reuse.
1.0.6 changed scanning method to always scan all available channels during connect. This results in results in connect taking about ~3 seconds instead of ~1. This patch changes the behavior to use WIFI_FAST_SCAN if client used a specific channel.
