depend on packaging module

[singingwolfboy]

Python's distutils module is deprecated, and has been removed from Python 3.12. Pinocchio is importing from distutils.version -- the recommended upgrade path for this is to switch to the packaging module, which includes utilities for version comparison.

Without this change, Pinocchio will not run on Python 3.12.

Hi ! This project doesn't usually accept pull requests on the main branch.
If this wasn't intentionnal, you can change the base branch of this PR to devel
(No need to close it for that). Best, a bot.

Hi @singingwolfboy, and thanks for this proposition.

I don't think it is worth to add a dependency on packaging for this. I'm not sure how different package managers and different python versions would like this (I'm especiallly thinking about ROS here)

hpp-fcl v1.7.7 is kind of old, so we could basically raise the required version, which is currently 1.7.3 according to our main CMakeLists.txt.

Another option would be to trivially parse this version number, with eg. tuple(int(i) for i in hppfcl.__version__.split('.')) >= (1, 7, 7)
