FAANG context

[henrietteharmse]

The context for FAANG has some similarities with that of HCA (see Issue 95).

The main difference is that their graph_restrictions, can form part of a oneOf restriction. Here is their faang_experiments_chip-seq_dna-binding_proteins.metadata_rules context:

The faang_experiments_chip-seq_dna-binding_proteins.metadata_rules context states that strings of text can map to one of the terms OMIT:0038500, NCIT:C177804 and NCIT:C34071, or a child of CHEBI:15358.
