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)

  Lines 55 to 59 in 5e86dbf

  	4. Install mapsforge-map-writer plugin (Osmosis Plugin)
  	* Download the [mapsforge-map-writer](https://search.maven.org/search?q=a:mapsforge-map-writer) plugin, click on "file_download" and select "jar-with-dependecies.jar".
  	* Put the .jar in this directory. Create it when it doesn't exist:
  	`~/.openstreetmap/osmosis/plugins`
  	* more information: https://github.com/mapsforge/mapsforge/blob/master/docs/Getting-Started-Map-Writer.md#plugin-installation

• 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

mapwriter plugin will be automatically copied to the correct location with #177.
The homebrew calls will not be automated at this time because it might be good to know what is installed and might not be good to automate / make things more difficult
