add manual climb

[kevinzwang]

I'd like to run this first because the numbers on the auto climb command has ambiguous numbers for tilt and for distance that we can narrow down with this command

Code failed on stop build day. Are fixes incorporated in this pr? Also, SmartDashboard keys don't match current naming convention (same as if it were a book title).

@kevinzwang Please address the merge conflict here.

It would make more sense and be cleaner code to negate climber.getEncDistance() instead of all the places where it is called, no?

[kevinzwang]

@SaltyJoke WPILib has a function to reverse encoder values

1. R.I.P. all logic and common sense
2. Thanks
   Please make sure I didn't miss anything

[dfang314]

The smartdashboard key values still need to be fixed (first letter of each important word is capitalized)
Also, this would take away our ability to run the auto-climb. We should have separate buttons for autoclimb and manual climb. Otherwise, looks good.

Also merge conflicts

[SaltyJoke]

Which button do you want for auto climb, which for manual climb?

[kevinzwang]

@doawelul fixed buttons and merge conflicts. please approve

[kevinzwang]

wait before you do that @SaltyJoke do the angle calculations work now?

[SaltyJoke]

The angle calculations work now if my geometry is correct.

Nice fixes
