Add a storage key comparison algorithm

recvfrom · web-flow · commit bea19b70f497 · 2022-02-11T18:58:53.000+01:00
This PR adds and exports an algorithm for comparing two storage keys. This will be useful for non-storage APIs that want to partition state using storage keys.

Also, adding my name to the Acknowledgments section since I forgot to do this with my previous commit. :D
