Gene grounding curation

[steppi]

This PR adds families and complexes for grounding some of the incorrectly grounded agent texts discovered in the gene grounding anomaly detection results. New entries include the Melatonin receptors, Proprotein convertases, Transglutaminases, Methyltransferases and subfamilies, Microtubule-associated proteins and subfamilies, Fatty acid binding proteins, Scavenger receptors, the Hexosaminidase family, the Beta-hexosaminidase complex, Procollagen-lysine,2-oxoglutarate 5-dioxygenase family, Eukaryotic elongation factors, Actin related proteins, Sp transcription factors, and Adenosine deaminase family.
