Drop Waypoints

[tjuav]

To symbolize a waypoint where a drop occurs, a new type of waypoint needs to be implemented: a drop waypoint.

Technical implementation:

• In PixHawk land, drop waypoints will function just like normal waypoints in a path - the plane will fly to the waypoint, hit it, and move on
• tj-uav/FlightSoftware (FS) will be notified of the new drop waypoint and will be given additional information (like which bottle needs to be dropped there) - actually dropping the waypoint will be handled in Drop Waypoint Handling FlightSoftware#15

UI Implementation:

• The submissions page from Submissions Page Implementation #149 will include buttons to create drop waypoints at certain locations and with certain characteristics (object, bottle to drop)
• Drop waypoints should also support manual creation through the Flight Data -> Map tab, where like loiters they will have additional popup configuration options (e.g. bottle number)
