Expanded input support for the wonderful DCS-BIOS.
I needed this for myself and kind soul that I am want to share it with the community ([FSF]Ian please feel free to use this in any future DCS-BIOS iteration, it would be an honour).
Support for a matrix of 2 and 3 position switches.
Support for multi-position rotary switches configured as voltage dividers (1k resistors between pins) up to 20 positions.
