Waveshare WM8960 Audio HAT

[paspo]

If you're using the Waveshare WM8960 Audio HAT, please take these notes into consideration:

• you have no LEDs and the default LED assignments are conflicting with some I2S signals
• the button is on different GPIO

So please use this configuration:

const (
//  no LEDs on this board, these GPIOs are free to use
//      don't use GPIO18 with this board
    OnlineLEDPin       uint = 22
    ParticipantsLEDPin uint = 23
    TransmitLEDPin     uint = 24
//  This is the correct GPIO for the button
    ButtonPin          uint = 17
)

Maybe take into consideration the possibility to not use the LEDs in code.

Also: thanks for talkiepi, it's awesome.
