DF cannot parse holes from geometries

[9and3]

DF cannot detect and parse holes in from Rhino geometries for now.

diffCheck/src/gh/diffCheck/diffCheck/df_joint_detector.py

Lines 103 to 105 in c4a4a3f

	if is_hole:
	# TODO: for future development get rid of error
	raise NotImplementedError("Hole detected, not implemented yet.")

The JointDetector should be able to take those in and parse them into DFBreps objects.

Here's the image, on top (no holes) it will work.
