ES8388 debug and AudioTools Example

[uutzinger]

• Added i2c bus check to request and acknowledgement of an i2c sensor
• Added Debug statements in the library as I was trying to find the i2c configuration issues.
• Changed audiotools-custom-max.ino to include my_pins.begin() and board.begin(), otherwise it will not work on ES8388 PCBArtists breakout board.

I probably added too many debug statements and the example ino is now larger than the usual short and compact ones for this and audiotools library. I recommend just to add the pin and board begin statements.
