Implement infrared sensor on climber for sensing whether we have actuated the top plate

[ana-tudor]

• [x] Do testing on a practice board with the IR sensor to see what values it needs to register red or blue light
• [x] Change the Climber class to utilize the IR sensor to return whether we have actuated the plate or not
• [x] Change the Climb command to stop the winch once we see that the plate has been activated. Figure out what we need to do in case the climber starts slipping.
• [x] Also add in functionality to slow down the climber motor if our current draw for the climber is above a certain level.

Not done, have to find color range still with AI

Have to find different sensor - VEX line trackers do not suit our purpose.

Updated requirements for issue.
