chore: allow to customize wakatime data range

[muety]

PR #871 changed the WakaTime fetcher in a way that it always requests data for whatever range the user has set as "Default Range" in WakaTime. However, chances are that a user may want a deviating range for her readme cards. Or she wants different ranges for different readmes in different repos.

Also, it makes behavior more predictable when using third-party sevice like Wakapi, that don't have inherent support for configurable "default ranges".

This PR allows to pass another, optional parameter to the WakaTime card to explicitly request a certain range.

Could somebody please take a look at this?

This looks good @muety can you add the range param to docs?

[muety]

Sure, it's done!

Btw, how am I supposed to resolve the merge conflict? Rebase onto master or merge it into my feature branch?
