ol-ext: Geohash

A geohash is a convenient way of expressing a location (anywhere in the world) using a short alphanumeric string, with greater precision obtained with longer strings.
The ol/geohash adds functions to convert a geohash to/from a latitude/longitude point, and to determine bounds of a geohash cell and find neighbours of a geohash.
Geohash can be used with permalink.
