Gear Handler Subsystem To Do List

- [x] Experimentally determine IR sensor threshold for gear capture, and update the code
- [x] Experimentally determine IR sensor threshold for peg detection, and update the code
- [x] Merge changes from Ryan once he pushes to master (he added a separate open/close button command instead of toggle, to support the drive team's request)
- [ ] Add limit switch status to smart dashboard
- [ ] Add a subsystem method to turn off the compressor, that we could either tie to an operator control button or call from the Climber subsystem if needed (to conserve battery power during a climb)
