Feature request: TTN Mapper should show tracker antenna gain

[sledzik1984]

A little feature request:

TTN Mapper should show tracker antenna gain (and of course there should be an option to filter antenna gains on map)

As everybody knows signal level reported by tracker with built in antenna will be totally different that signal reported by tracker with external antenna (for example in-car)

I think that this should be easy to implement after updating "ingest API". Trackers source code also should be updated to send antenna gain provided by user.
