My library for the Microchip MCP23017 and MCP23018 I2C I/O expander ICs

Hi fellow biker!

This is interesting, I just found this topic when I was wondering how to expand my Wemos mini.
I twill try your library today, just woul dbe nice to know if you have done any modifications? It's been
a while since that post. Thanks!
