CoMaps: remove TetheredNet AF
Since release 2025.12.19-11 the maps download url is customizable via a setting.
Note that it allows to mirror map files only at the moment, i.e. the maps should be exact copy of official ones (checksums are hardcoded into the client still). Downloading custom maps is not supported yet (there are compatibility concerns to take care of). Still, this is a first good step into this direction!
