MapGeometry - Refactor class structure

[orbitusii]

To better support behavior outlined in #3, MapGeometry needs a refactor

• Needs to retain Vector64 coordinate storage
• Needs to retain SKPath caching behavior
• ADD reference/string to original Kml file
  • If imported, this won't change
  • If the geometry is edited, this MUST change to a new file, ideally in AppData, with "_edited" or something similar added to the end of the name but before the extension
  • If editing already-edited geometry, it should NOT add "_edited" again - no "File_edited_edited_edited_edited.kml"
  • Edits should set a boolean value that informs LOKI it needs to save this changed Geometry to a KML file on application close
