    --- Rotary Encoder Mappings ---

    Encoder mappings go from leftmost encoder to rightmost encoder on the physical board.
    index 0 is the the optional leftmost encoder on the left half, index 1 is the right encoder
    on the left half (by the thumb keys), index 2 is the left encoder on the right half (by the
    thumb keys), and index 3 is the optional rightmost encoder on the right half.

    If you are only using the 2 required encoders by the thumb keys, you only need to worry about
    index 1 and index 2.

    Note that the key to be sent for counter-clockwise rotation (CCW) goes first and then the key for
    clockwise (CW) within ENCODER_CCW_CW.
