Updated split encoders so indexes are based on left hand encoders first (#6382) 

* Updated encoder.c so that split encoders are indexed based on left hand encoders first.
This ensures when swapping master sides that code logic based on encoder index doesn't change.

PR Review fixes

* Removed extra define
