Migrating to Mapbox API V10

[PWRxPSYCHO]

Part 1 of issue #359

Working on the migration to V10 of MapBox

Key things to note in this PR:

• Min SDK version has been bumped from 15 to 21
• com.github.mik3y:usb-serial-for-android has been updated from v3.0.0 to v3.4.3 (This might cause issues so we can attempt to revert if necessary)

Work that has been completed:

• Upgraded MapBox dependency
• Updated map_view.xml to reference to new version
• Updated the rendering of MapBox in the MapFragment.kt file
• Updated adding Layers, Source, & Image to Layer View
• Updated Gesture Control
• Updated Nodes Position
• Updated Camera Movement (and initial load zoom level)
• Removed old dependency

I do not have 2 GPS capable devices to test multiple nodes. So that should be tested before this gets merged. If there are any issues I would recommend whoever has the devices makes the changes so that it can be tested more efficiently.
