New features:

• Single Extruder Multi-Material (SEMM) Support: Purge Tower/Ramming/etc (Compatible with ERCF/TradRack/MMU)
  OrcaSlicer originated as a fork from BambuStudio, which, despite being based on PrusaSlicer, had removed the multi-material capabilities for non-Bambu printers. This led to OrcaSlicer initially inheriting this limited support. However, in this release, we have reintroduced the SEMM feature from PrusaSlicer. Users can now print in multiple colors on any printer, whether it's equipped with Prusa MMU, ERCF (from the EnragedRabbitProject), Annex TradRack, or a simple N-in-1-out extruder.
