Fix Pinball Shooter

[esloan]

My notes on how that subsystem (and the compressor subsystem) should work.

Solenoid going backwards at the same time as mysterious latch (locks)
Piston goes back (one goes forward one goes back) and flip on relay

To hold back springs: turn on electromagnet

---

Turn back solenoid
Turn on electromagnet (relay)
Wait until fully back (limit switch)
Turn forward solenoid

The two subsystems for the pinball shooter and the compressor should be merged

Record which state it's in: where the piston and latch are (boolean or enum)

Add sensors into subsystem: two limit switches: one on each end

Make a shoot command
