Make a file with unique protein sequences and associated IDs

[inodb]

Maybe we can create a file that has one row per unique sequence and associated IDs? Each column can e.g. be a database so you get something like

unique protein sequence	ensembl_grch37_vxx_protein	ensembl_grch37_vxx_transcript	ensembl_grch38_vxx_protein	ensembl_grch38_vxx_transcript	uniprot
RRRRR	ENSPxxx	ENSTyyyyy	ENSPxxx	ENSTyyyyy	Pzzzz

We can then reuse this file for uniprot, oncokb and hotspot transcript assignments. It also allows to easily add other potential protein resources
