Update jupyter-packaging to 0.10.6

[ellert]

The import of bdist_wheel is optional:

ipyparallel/setupbase.py

Lines 46 to 49 in da60bff

	try:
	from wheel.bdist_wheel import bdist_wheel
	except ImportError: # pragma: no cover
	bdist_wheel = None

Just like the use if it is None protected here:

ipyparallel/setupbase.py

Lines 577 to 578 in da60bff

	if bdist_wheel:
	cmdclass['bdist_wheel'] = wrapper(bdist_wheel, strict=True)

The use here must be None protected too:

ipyparallel/setupbase.py

Line 145 in da60bff

_make_wrapper(bdist_wheel, pre_dist, post_dist)

setupbase.py is vendored from jupyter-packaging, and shouldn't have any patches not already accepted upstream. I'd recommend submitting this patch upstream, though, since I think it's still correct. We can update here once it's been accepted there.

That said, bdist_wheel is not optional, and is explicitly required in a way that it should be assumed to be available prior to running setup.py. If you've run into this, it probably means something is using outdated build tools (i.e. doesn't support PEP 518). Can I ask how you encountered it?

The change was merged upstream.
I have updated the PR to import the updated version.

Thanks!
