Fiber-seq: hide the container by default, and split the five GM lines out
into a Rare disease sample class.  Max asked for superTrack on rather than
on show, since the track covers much the same ground as ENCODE DNase and
does not earn a slot in everyone's default hg38 view.  The five
lymphoblastoid lines GM25455, GM25456, GM27730, GM28570 and GM28572 had
been filed as Common Cell Line; Andrew Stergachis says they are rare
disease cases consented to broad genomic data sharing and the first of a
batch the lab intends to keep adding, so SAMPLE_CLASS_COLORS gains a third
entry and the facet now reads 20 HPRC, 16 Common Cell Line, 5 Rare disease
sample.  refs #36210

 sequence, the added adenine methylation and the native CpG methylation from the same molecule.
 Because the reads are long enough to span heterozygous variants, they can be phased to a
 parental haplotype, giving a chromatin picture for each allele separately rather than an average
 of the two.

 The accessibility this measures is the same property that DNase-seq and ATAC-seq measure, and
 the tracks here can be read much as those are. The difference is that Fiber-seq reports it one
 molecule at a time, so a value is a fraction of molecules rather than a pile of cut sites, and
 it can be split by haplotype.
