Geocode search windows can incorrectly convert doubles

[mihakrajnc]

When using the geocode search window to find locations, in some locales the gps coordinates will get formatted with a comma instead of a dot, e.g.:

"42,23551, 33,123555" instead of "42.23551, 33.123555 ".

AbstractMap will then not be able to parse the coordinates.

Note: If this is a bug or support ticket, please provide the following information:

• Unity version: 2018.1.0b12
• Mapbox SDK version: 1.4

this is probably due to local device culture info so we should parse values with culture info set correct instead of letting .net use device culture.

I guess this is good to close after @atripathi-mb's fix above.
