Three more Imprinting subtracks on hg38: Geneimprint, Akbari iDMRs, OMIM

Geneimprint: the human catalog of imprinted and candidate imprinted genes
from geneimprint.com, 274 genes. The catalog gives only a cytogenetic band,
so symbols are resolved against the HGNC track, with fallbacks for small RNA
clusters and for symbols HGNC has retired.

Akbari iDMRs: the 192 imprinted differentially methylated regions that Akbari
et al. 2023 (PMID 36777186) compiled from five genome-wide studies. Their
published coordinates are 1-based inclusive, not bed, as their own PatMat
reader shows, so the starts are shifted.

OMIM: the 459 loci that OMIM curates as imprinted. That call is published only
through GeneScout and is in no OMIM download file, so the input is a GeneScout
export made by hand from a browser. OMIM phenotype entries, which are mapped
disease regions up to 90 Mb rather than gene positions, are left out.

Also unifies the color scheme across the collection, so vermillion always means
the maternal copy, blue the paternal copy and gray no parent of origin, and
relates the collection to the Human Methylation Atlas.
