Library for using MCP23017 port extender interrupts

Hi,

I have just developed a library focused on interrupt driven input processing of MCP23017 events.

My library is based on the Adafruit-MCP23017-Arduino-Library, that already implements the communication protocol.

With the MCP23017int library you can define callback functions for handling input events.

Note, that the library is not jet requested to be listed from the library manager, as it is not well tested. So please fill test it. :wink:

Cheers,
