Hide incompatible stations in planner

[Capkirk123]

What it says on the tin. There are a lot of launchsite tracking stations cluttering the planner, which make it difficult to find the desired ground station if you want to check one connection in specific. This will probably only be worsened by the addition of new tracking stations with unique characteristics (Skopos, or one of the ground station PRs).

Hiding all antennas except those operating in the same band as the one currently selected on the antenna the planner is focused on would make finding the desired ground station much easier.
