Adding ENCODE4 Integrated Regulation tracks for hg38 (wgEncodeReg4) and mm10
(encode4Reg). Each supertrack contains 6 organ-averaged multiWig signal tracks
(H3K27ac, DNase, ATAC, H3K4me3, CTCF, Transcription) and 3 bigComposite
faceted individual experiment composites (Epigenetics, RNA-seq, TF ChIP-seq)
using S3 URLs and the new faceted composite UI. hg38 also includes a TF rPeaks
track. ENCODE3 regulation tracks are release-tagged to show a snowflake
deprecation notice on alpha while remaining unchanged on beta/public. Includes
generation scripts, makedocs, HTML descriptions, relatedTracks, and metadata
TSVs. refs #34923
