Frontend sends "24bit/44.1kHz" format from track metadata, but
parse_quality fell through to default UltraHiRes for unknown formats.
This caused unnecessary API quality fallback cascades (3 calls per
track) and cache mismatches where cached 24bit/44.1kHz data was
discarded for re-download that returns the same quality.
Now parses "XXbit/YYYkHz" format and maps to the correct Quality
level, requesting exactly what the track offers.
