Notes sometimes self-launch

[jamesdooley4]

During drive practice this week, sometimes notes held in the launcher will spontaneously launch out of the robot. It seems to happen more frequently with non-orange notes, but also happens with orange notes. Mech is looking for a 2nd feeder sensor to wire to another DIO port, but it'd be good to also look into code changes to make feeder/launcher tolerate the sensor losing note detection for a "brief" time once a note is being held.
