## Description of change
Add a new option that allows absolute position analog input, such as
SDVX controller knobs and IIDX turntables, to be bound as input for
Polaris Chord faders.
In practice this means turning a knob counter-clockwise results in fader
being held left (relative to velocity), and vice versa.
## Testing
Tested using FauceTwo and a mouse.
