Add support for CURIE/URI normalization

[gaurav]

@matentzn asked for:

add support for curie/uri normalisation with the curies package (https://github.com/biopragmatics/curies) and in particular extended prefixmap support (https://curies.readthedocs.io/en/stable/tutorial.html#loading-extended-prefix-maps). This allows people with different prefix preferences for curies to use the service seamlessly

This would be great to include -- in our case, we would default to using the prefix map from the Biolink model to expand CURIEs to URLs, and then potentially support a second prefix map that could turn them back into CURIEs for another system if needed. We would probably start with putting this into the KGX export, and then we could add it to additional outputs as needed.

Awesome!
