Fetch column lists for standard formats from biodatamodels

[kevinschaper]

In the Xenbase branch, I have a start at the idea that a source config can specify a standard data format rather than having to explicitly list columns - but initially it only has a couple of hardcoded format examples (GPI & OBAN).

Rather than hardcoding, we could fetch them from https://github.com/biodatamodels

(and maybe we can populate models at biodatamodels as we need them)

Looking at GPI as the example, it doesn't look like I can fetch column names exactly, since the slot names and column names aren't the same. Some are equivalent other than formatting, but not all.

slots:
db object ref
db object symbol
db object name
db object synonyms
db object type
db object taxon
encoded by
parent protein
protein containing complex members
db xrefs
gene product properties

vs columns:

DB
DB_Object_ID
DB_Object_Symbol
DB_Object_Name
DB_Object_Synonym(s)
DB_Object_Type
DB_Object_Taxon
Parent_Object_ID
DB_Xref(s)
Properties

hpoa might be a good use/test case for this - https://github.com/biodatamodels/ontology-associations/blob/main/src/schema/hpoa.yaml
