pymata_aio v1.5

RELEASED!

Version 1.5 of pymata_aio has been released on github and pypi.

This release allows callback functions to be user selected as asyncio coroutines or direct calls for both pymata_core (the pure asyncio version of the library) and pymata3 (the proxy library for pymata_core).

In addition, some minor bugs were fixed that were not yet reported, but were discovered by me.
