Support Switching Map Types

[CoryFoy]

Is your feature request related to a problem? Please describe.
When displaying the map we don't allow switching between the map types. There are cases where a Satellite View is preferable to the roads view.

Describe the solution you'd like
In Settings allow switching between the various map types. Additionally move toggling the map to the bottom of the Settings Screen along with any map controls.

Additional context
While display a map seems like a great feature, not every use of TAK Tracker needs the map to be displayed

Fixed in PR #18 and will go out with the next TestFlight release
