add feature - parse tempo directly from score (musicxml) and make it option for tempo adjustment

[laurenceyoon]

• Adds MusicXML tempo-marking parsing (e.g., “Allegro/Andante”) with simple/compound meter handling to derive quarter-note BPM (matchmaker/utils/misc.py).
• Reorganized tempo selection in Matchmaker:
  • priority becomes 'user tempo' → 'score marking' → default 120;
  • performance-based tempo adjustment now only when adjust_tempo=True (matchmaker/matchmaker.py). -> I'm considering not using it in our benchmark test.
• Injected tempo marking into tests/resources/Bach-fugue_bwv_858.musicxml for easy testing.

Below is list of text tempo marking mapped to certain BPM:
