tro_annotate --read-tros: TRO-Handkorrekturen aus BricsCAD, Staubereiche vor dem TRO

- Marker tragen KEY (ID der ID-Datei) und SLOTS (Bauteil je Slot), die
  Zeichnung die Bauteiltabelle SPS_SKEL_PARTS (XRECORD) fuer "Im Plan
  waehlen" im Dialog TRO_EDIT (dxfmakros)
- --read-tros schreibt geaenderte, neue und geloeschte Marker als
  Abschnitte edit/edit_add nach cfg/tro_overrides.ini; tro_flow.apply_edits
  wendet nur diese Arten an (Bauteile mit Lage, exportfest)
- --emit-lisp schreibt dazu *TRO-SLOTS* und *TRO-SLOT-KINDS*
- model: Lagerlinien zaehlen je TRO (Katalog nur Vorgabe), Mubea-Speicher
  jetzt 20 Linien (Golden-Datei)
- Staubereich als stehendes graues Rechteck direkt vor seinem TRO-Marker
  (jam_abstand statt jam_versatz); Marker 150 mm, Text 120 mm
