Add missing dryer cycle labels for DV90DG6845LHU5 (issue #244)

Codes 51 (Eco Cotton), 53 (AI Dry+), and 4e (Self Dry) were confirmed by
the reporter selecting each program on the physical appliance and reading
back the resulting raw course code, same table (Table_03) as the existing
issue #80 confirmations.

Also fixes an import-sort lint error left over in by_type/dehumidifier.py
and a stale comment in dryer.py claiming codes 21/4c were still
unidentified when the catalog already had them.
