[FEAT] Refactor a lot to decouple and make maintenance easier (focus …

…osm_maps_functions.py) (#152)

* import file_directory functions one by one

- and not by importing the whole file "as" fd_fct

* create OsmData object and insert into class OsmMaps

* move check for -co and -xy to input.py

* shuffle a lot

* go throught calc_border_countries also when no border countries are wanted

* break OsmData in small pieces

* refactor border country calc + fix unittests

* force_processing refactoring, all checks in OsmData now!

- move to function process_input_of_the_tool
- move corresponding stuff from check_and_download_files also
- additional needed changes - mainiy in downloader.py
- adjust tests & do nearly refactoring

* import needed functions + pylint findings

* refactor imports to "single import" and not the whole file

* fix pylint finding

* Bump to version v2.1.0a13
