Add map filter check to !globalcheck

While it is possible to solve inside GOKZ, this should be done from GlobalAPI side. Since GlobalAPI repo has no issue page, I figure might as well put the issue here.

What would the global check check on the map filters? That there exists a single filter at least for the maps main course, or?

Doesn't make much sense to have that kind of check I would say, since its not an issue with the server that filters are not there, so why check it on the server?

Checking the filter on the server is a good way to ensure your run does get uploaded to the API and is not wasted. Happens a lot for VNL players where they do a very hard map (previously believed to be not possible) just to realize there is no filter for the correponding courses.

That said, I realized that the combination of run types, modes and courses might make this filter check more complicated.
