Pycatia

* added option to initialise the Application object with pythoncom.CoInitialize().
This is required for when using pycatia in a threaded context. To use this
feature you would do `caa = catia(co_initialise=True)`.
* fixed name conflict in RemoveFace().

* fix type hinting issue with python 3.9. 194 mokrueger
* updated Factory_2D.create_spline() so that it will now accept a tuple of
control_points instead of their com_objects. 199 mokrueger

the pycatia user is using a modified com interface provided by Dassault.
195 mokrueger.

a quirk with regard to its usage. See the GitHub issue 202 for further

find them. These are labelled for example `:param int value: enum cat_circular_pattern_parameters`.
