[Feature Request] mwp should implement a GCS-NAV PH mode

[stronnag]

As INAV Wiki article.

• [x] Provide a dialogue to allow the user to
  • confirm they've enabled GCS_MODE (via switch)
  • drag a icon to the desired location on the map
• [x] Click OK to send the location as WP#255

Note this would require that MSP is being used as the monitoring telemetry protocol.

Now merged into 'development' branch (d426a95f). Under the Edit menu, there is a new option Set FollowMe Point. Until you're armed and in POSHOLD this is not sensitive.

Now armed, but not POSHOLD (Orange Home Icon showing), still not sensitive ...

Now in POSHOLD. note the Green POSHOLD icon ... menu option is sensitive!

Clicking the menu option invokes the FollowMe dialog:

The FollowMe desired location is indicated by the second green icon (with the ⨁ symbol). This may be dragged to the required location. An altitude, relative to home may also be set, 0 means don't change altitude.

It's probably 6 years since anyone has used this sort of INAV functionality, so take care. In particular, I'm not sure how well the altitude item works (in the firmware, mwp sends the correct data). So start will plenty of altitude and 0 as the setting.

Note that this has not been flight tested; the images and data tests have been done using the INAV SITL (software in the loop), i.e. running INAV firmware as a desktop application, with fl2sitl as the (trivial) sensor provider and ser2tcp allowing a physical RX/TX to be used with the SITL.

In the event that someone flight tests this, a blackbox log would be appreciated.
