Deprecate brainbox.processing.bincount2D

[chris-langfield]

From the discussion in int-brain-lab/ibl-neuropixel#13 we are going to move bincount2D to iblutil.

This replaces brainbox.processing.bincount2D with a call to the imported version from iblutil and adds a warning.

Also updates the requirements to iblutil 1.6.1, which contains the replaced method. (int-brain-lab/iblutil#19)

Looks good. Just change the requirements to a minor release. For the other rigs I've been raising both a DeprecationWarning and a logger warning in case users turn off the ibllib logger but that's overkill to be honest. We also usually include a print statement of the traceback because it's sometime very difficult to find the call to that function, like this:

ibllib/brainbox/behavior/wheel.py

Lines 88 to 89 in 381d648

	for line in traceback.format_stack():
	print(line.strip())

It's also super annoying though (which may be a good thing). Personally I don't think it's particularly necessary.

Finally, Olivier adds something that breaks the test as a reminder to remove the deprecated function e.g. 2f6a13e. I just set a reminder in Slack once the branch has been merged for release.
