Store CAFs from input VCF

[jsstevenson]

Feature description

functions.ingest_vcf has a stub for storing each CAF in the anyvlm DB:

AnyVLM/src/anyvlm/functions/ingest_vcf.py

Lines 87 to 96 in 48fed0a

	for batch in _yield_expression_af_batches(vcf):
	expressions, afs = zip(*batch, strict=True)
	variant_ids = av.put_allele_expressions(expressions, assembly)
	for variant_id, af in zip(variant_ids, afs, strict=True): # noqa: B007
	if variant_id is None:
	continue
	# make call to object store method for putting CAF here
	# presumably build the CAF object here + call the insert method with it
	# may need to alter zip() if the insert method expects a full variation
	# instead of just the ID

This needs to be replaced with CAF construction from those args + upload into DB

Use case

Using anyvlm

Acceptance Criteria

Given that an uploaded VCF has been decomposed into alleles + AF annotations, these data need to be reconstituted as CAFs and added to AnyVLM storage
