Wheel QC should check polarity

[k1o0]

The check_wheel_move_during_closed_loop QC test only asserts that the wheel was moved a sufficient amount in any direction. We've since learned that on some rigs the encoder was wired incorrectly such that the extracted wheel direction was inverted. The QC check should be modified to test that the sign is correct for the recorded choice.

	def _wheel_move_during_closed_loop(re_ts, re_pos, data, wheel_gain=None, tol=1, **_):
	"""
	Check the wheel moves the correct amount to reach threshold.
	Check that the wheel moves by approximately 35 degrees during the closed-loop period
	on trials where a feedback (error sound or valve) is delivered.
	Metric:
	M = abs(w_resp - w_t0) - threshold_displacement, where w_resp = position at response
	time, w_t0 = position at go cue time, threshold_displacement = displacement required to
	move 35 visual degrees
	Criterion:
	displacement < tol visual degree
	Units:
	degrees angle of wheel turn
