Change HPO term storage

[MattWellie]

Fixes

• Not sure if this is required, setting as a draft
• I used to store HPO terms as a list of Strings. Recently this changed to HPO - Text Description. That packaging is going to make it harder to pull out just the HPO terms

Proposed Changes

• Takes the list of compound Strings and changes it to a dictionary of {'HPO': 'Description'}
• Later it should be pretty easy to pull out just the HPO terms if required for phenotype matching

Checklist

• [x] Linting checks pass

How would you feel about aligning with the {id: "HP:0012469", label: "Infantile spasms"} style format from phenopackets?

Do you want this in now? Seems like a good idea to me.

Can do! Do your pheno-matching changes rely on this? The conflicts are wild, will try and clean that up
