Move to using the dtocean-data package for non-code data

[H0R5E]

This PR changes the way that the non-code data required for this package is discovered. It now looks for configurations files generated by the dtocean-data conda package or an installation created by the installer retrieved from the https://github.com/DTOcean/dtocean-data repository.

Bump to version 3.1.0
