JSON parsing is not reliable

[aylen384]

When parsing the google-json this script may work. But when the json has eg. newlines or spaces at some positions, which are allowed json-syntax, the parser will fail.

Therefore an external parser like https://github.com/dominictarr/JSON.sh should be used.

This would allow using other geolocate-backends like my one:
