macOS: automate the installation even more // setup.py file?!

[treee111]

Is your feature request related to a problem? Please describe.

• on macOS there are some steps during installation that need to be performed manually
• the check of the successful installations along with giving hints how to perform the installation would be good

Describe the solution you'd like

• automate this step every time, wahooMapsCreator is running or only the first time (setup.py might help) https://github.com/treee111/wahooMapsCreator/blob/5e86dbf693570f38356c5abeab722a3985d1de30/docs/QUICKSTART_ANACONDA.md?plain=1#L55-L59
• check, if the brew parts can be established via cmd... calls
  • could be done via python -m wahoomc.init function
  • other initialization stuff could be included there as well
