[chirp_users] installing CHIRP-next problems

[Jeffrey Vian]

attrdict was definitely used by wxpython.  I installed it using pip, then
the noted errors popped up.
I was able to work around the problem by adding the following lines to
`/usr/lib64/python3.11/collections/__init__.py`

"
from _collections_abc import Mapping
from _collections_abc import MutableMapping
from _collections_abc import Sequence
"

After adding those lines for the modules that wxpython was complaining
about the install completed.
Note that nothing I found in the install instructions said that wheel was
needed, but as a matter of course I always install wheel and wxpython also
used it, building several wheels for the packages installed.

Your note seems to indicate that those modules would not have erred with
python 3.10 but definitely did with python 3.11.
