github.com/ringsaturn/pk (go): Package pk provide part of https://github.com/Placekey/placekey-py features in pure Go. Most of codes translated from Python SDK. See details in https://docs.placekey.io/Placekey_Encoding_Specification_White_Paper.pdf  Placekey has two parts: `what` and  `where`.  The `where` part. The core of `where` part is cut 21 bits of 64-bit integer which is a H3 integer, only use 43 bits left. Because the resolution is a const `10`, so each H3 id under the same resolution could remove common info. Then use alphabet represent the 43-bit integer as the `where` part of the whole place key.  The `what` part need use Placekey's API. Check API doc https://docs.placekey.io
