Subject: geocoder: Implement MapmyIndia Reverse geocoder

MapmyIndia reverse geocoding is very helpful for the Indian
subcontinent, It's "distance from nearest POI" detail embedded in the
formatted_address field of the response is quite impressive for the
reports.
The Confirgurations required to be added in the config file
"traccar.xml" are

    <entry key='geocoder.enable'>true</entry>
    <entry key='geocoder.type'>mapmyindia</entry>
    <entry key="geocoder.url">https://apis.mapmyindia.com/advancedmaps/v1</entry>
    <entry key="geocoder.key">YOUR_KeY</entry>
    <entry key="geocoder.format">%f</entry>
