Lib/GeocodeLib updates

* comment incorrect, pause time in microseconds
* option for number of `repeats` vs. hardcoding at 5
* new property for `reachedQueryLimit` which disables all future `geocode`/`reverseGeocode` calls in this run
* `reset` will clear `reachedQueryLimit`
Merge branch 'master-upstream' into dev-ahm
