feat(nativegeocoder): change return type to array and add options param

[sebastianbaar]

For making the API more robust for future changes and new features I changed the return type of both methods to an array and added an 'options' param.

• The result Object of nativegeocoder.reverseGeocode is an Array.
• The result Object of nativegeocoder.forwardGeocode is an Array.
• Add options param for both nativegeocoder.reverseGeocode and nativegeocoder.forwardGeocode for setting locale & max result objects
