Fix crash when Map notification is provided invalid latitude/longitude (

#1307)

- Fixes a crash when `latitude` or `longitude` are String types but not able to be converted to Double/CLLocationDegrees.
- Adds support for Int or Float-based `latitude` or `longitude`, e.g. what native templates would provide were it not currently broken.
