Possible esp8266 support

[panilov7]

I want to use this library on the esp8266, but I'm stuck as the esp8266 does not support the _thread module (micropython/micropython#3667).

Is it possible to remove the use of the _thread module and use an alternative to threads?
Something like asyncio on CPython or uasyncio on Micropython, which is supported by the esp8266.

Thanks!
