Simplify imports in pycatia with improved module structure

[HubertDomaros]

Problem
Currently, pycatia requires importing each class from its specific module, leading to lengthy import statements when building something more complex:

from pycatia.mec_mod_interfaces.part import Part
from pycatia.mec_mod_interfaces.body import Body
from pycatia.mec_mod_interfaces.hybrid_body import HybridBody
# ...many more imports

Solution
I autopopulated init.py files for each module with help of utility script (https://gist.github.com/HubertDomaros/9d1a03bf0ebc7080b40604712147b3ca) to expose all classes within that module. This allows for much cleaner imports:

from pycatia.mec_mod_interfaces import Part, Body, HybridBody

This change maintains backward compatibility while significantly improving developer experience by reducing import verbosity.

This is something I attempted myself sometime back. But, as soon I entered the circular import error hell I gave up. It appears that this is also an issue here.

Have you tried running the tests?

pytest -v tests
