[DEV] install: introduce config file .config.json // store python module version

[treee111]

This PR…

• introduces ~/wahooMapsCreatorData/.config.json file to store values about the last wahooMapsCreator run such as the version of the python module

Considerations and implementations

Having this in place we can implement release-based changes such as remaning of files, directories. Moreover we can speed up processing by skipping things which are done once per each version (if there is anything, might be more interesting per country and version).

How to test

1. run wahoomc as normal and check output
