ESP32 Hardware SPI Improvements - Options for using both SPI peripherals, and DMA (#441)

Browse Source 
* Fix header file comment

* Add TwoWireHspiImpl and Example

* Add start of TwoWireEsp32DmaSpiImple (Currently just able to use HSPI and VSPI in parallel, no DMA)

* Update names for TwoWireEsp32DmaSpi and set set spi_bus using template not constructor

* Update example with new functionality and bugfixes

* DotStarEsp32DmaSpiMethod -

* Add 5MHz option to all SPI-based classes

* DotStarGenericMethod - Give option to use Vspi alias of Spi class if wanting to specify which SPI peripheral is used on the ESP32
- Add missing DotStarHspiHzMethod

* TwoWireHspiImple - bring up to date with applySettings() method

* DotStarTest_Esp32Advanced example - update to show how to change clock speed at runtime
- Remove commented out pins cluttering up example

* DotStarTest_Esp32DmaSpi example -
