Adds a set of unit tests for dropzone plan generation and GPS <-> meter offset conversions with associated visualizations.
Also fixes a bug I found while writing these tests.
Test Plan
I spotchecked the visualizations produced by the tests and they looked good. Also, the bugfix now means the club field dropzone scan works properly in SITL.
