magicbot: Allow integer feedbacks

[auscompgeek]

This inspects the return type hint on @feedback methods to determine what topic type they should publish. This allows publishing integers to NetworkTables instead of floating point numbers.

(This currently isn't possible due to the backwards compatibility in pyntcore's setValue method preferring to upcast integers to doubles.)

If the types are incompatible at runtime, the robot code will crash, e.g. in tests:
