Support for other feeders

[trev]

Hi, I did a bit of work to read the feeder indexing commands from an RV and support an alternative feeder.

This is the first version I have built to get a feel for how well it will work. The Arduino mega with shield can support 48 lanes which are decoded from RV Bank and Lane data.

This feeder built is linked below and I adapted the code to read in RV indexing commands on one UART and feed it into the existing code to drive the appropriate feeder.

Hopefully I will progress further to get something robust enough to get some proper testing done on it.
