Add --except PATTERN option and update documentation

- --except filters albums by directory name (glob or substring, repeatable)
- README.md: new options table entries, new cover sources, updated pipeline,
  corrected test count (33), added batch example
- BEDIENUNGSANLEITUNG.md: new options table, sections E (batch+except),
  F (--status), LASTFM_API_KEY env var, corrected test count
