Feature request: moar tag types for DOP

[smathermather]

I could be misreading, but as far as I can tell, a limited number of DOP tag estimates are used. The DJI Mavic 3EM writes in the following form:

Rtk Std Lon                     : 1.23673
Rtk Std Lat                     : 1.19709
Rtk Std Hgt                     : 3.91458

Propose we build in logic to support this and other formats for tags. Happy to update get_gps_dop to support more tag types, but figured I'd open an issue first since it's friday and my brain is mush.

Todo: GitHub that auto closes any issues I open on Friday afternoon.
