LocoIO update

I’ve built another HDL LocoIO board. Hope to configure it using JMRI 4.12.

Not yet in JMRI 4.11.6. I’m working to get the tool operating with the newer hardware.

Update: JMRI 4.15.5 contains more options to configure these boards, as well as HDL LocoBooster and LocoServo boards (ports 1-5 to start with).

Please report your results!
