Same as NeoEsp8266Uart800KbpsMethod but using a longer delay as required by this chips.
## NeoEsp8266AsyncUart800KbpsMethod
Use this instead of Neo800KbpsMethod to force your sketch to use the Uart to send data asynchronously.
NeoEsp8266AsyncUart800KbpsMethod only supports the TXD1/GPIO2 pin. The Pin argument is omitted.
**WARNING:** With this method, Serial and Serial1 can not be used due to the ISR is not shareable.
**CAUTION:** With this method the `Pixels()` method will return alternating pointers after each call to `Show()`; so the pointer returned should not be cached or retained between calls of `Show()`.
NOTE: Due to the varied board layouts for Esp8266, even though the pin maybe exposed, it may not be usable due to some custom feature on the board you use. If you find it not working, you should review the hardware schematic of your board and confirm the pin is not used for other purposes that interferes with it being used for NeoPixelBus.

_Thanks to unaiur for providing the implementation._
Due to using the TXD1/GPIO2 pin, the Serial1 object can not be used with the method and must be avoided. The primary serial object "Serial" is available for both read and write.
Use this instead of Neo800KbpsMethod to force your sketch to use the Uart to send data asynchronously.

Same as NeoEsp8266AsyncUart800KbpsMethod but running at the older and slower data rate.
