Dan Albert 722ec00076 Add radio information for more aircraft.
Adds the following:

* AJS37
* AV-8B
* JF-17

This does move the preset channel allocation logic into its own class,
since we need to customize that behavior for the AJS37 since it has a
rather unique preset channel layout (see the comments in
`ViggenRadioChannelAllocator` for details).
