Add mavlink camera trigger when GoPro not connected

[Pedals2Paddles]

When there is no GoPro connected, the GoProManager.py handleRecordCommand function should send the mavlink DO_DIGICAM_CONTROL shutter command. That way if the user has some other camera connected, the same controls can trigger that camera's shutter. This will respond to the paddle button and the app shutter buttons. The command should be inserted here: https://github.com/OpenSolo/shotmanager/blob/master/GoProManager.py#L386

Good idea. I wonder though, does DO_DIGICAM_CONTROL work outside the context of a mission?

[Pedals2Paddles]

Yep. It is also in GCS_Common.

Yes, this is exactly what I was looking for. Does anyone have a code example for sending DO_DIGICAM message?
