Title: Add simple func to allow calculating all adjacent geohashs in a single call

Hi,

Thanks for implementing the algorithm! This is just a quick addition to allow a single call to return all surrounding hashes. Results in a []string with eight values representing all surrounding hashes for a particular centre hash.

Regards,
