[FIX] Prevent initialisation of the graphical GUI on WSL (#72)

- Prevents the initialisation of the graphical GUI on WSL.

* Introduce Pull Request Template

* [FEATURE] Add check for required input parameter for CLI and GUI (#41)

- now not only for GUI but also for CLI the country argument is checked
- added a check at the start to see if a country is to process is specified. Otherwise closing the GUI without selecting anything resulted in a runtime error.

* [FEATURE] Enhance check for existing (already downloaded) polygons and .osm.pbf files (#43)

- use the files modification date, not the creation time. On windows this seemed to occasionally see newly downloaded files as the ones they replaced.
- check for a full match instead of doing a wildcard match while checking for existing maps. This prevents matching to multiple maps like australia and australia-oceania.

* Delete PULL_REQUEST_TEMPLATE.md

* Delete wahoo_map_creator.py

* Check if we are running in WSl. If so prevent starting the Gui
