pybigtools bigbed write appears to store chrom as "rest"

[nvictus]

import pybigtools as pbt

f = pbt.open("/tmp/foo.bb", "w")
f.write(
    {"chr1": 1000, "chr2": 1000}, 
    [
        ("chr1", 0, 100, "foo\tbar\t3"), 
        ("chr2", 100, 200, "xxx\tyyy\t1.0"),
        ("chr2", 200, 300, "zzz\twww\t1.0")
    ]
)
f.close()

f = pbt.open("/tmp/foo.bb", "r")
list(f.records("chr2"))

[(100, 200, 'chr2'), (200, 300, 'chr2')]

print(f.sql())

table bed3
"Simple bed"
(
    string chrom;        "Reference sequence chromosome or scaffold"
    uint   chromStart;   "Start position in chromosome"
    uint   chromEnd;     "End position in chromosome"
)
