LEGO Exchange Format Importer (.lxf/.lxfml)

This importer is derived from sttng's ImportLDD Add-on with a few changes:

• Support for importing one or multiple LODs at a time
• Enchanced Brick DB handling:
  • Support for defining a path to any Brick DB via Add-on Preferences
  • Direct support for using LU's brick db without needing to extract it manually
    • You can use the client/res/ folder directly as a Brick DB source
    • the brickdb.zip will automatically be unzipped for you if it's not already
• Dropped support for using LDD's db.lif directly since it doesn't provide LODs
• Consolidated color support for LU's color palette:
  • Colors outside of LU's supported palette will be coerced to the closest color
  • Please report any instances of missing colors so that they can be added
• Missing data handling:
  • Bricks missing from brick database will be skipped
  • Completely missing colors will be set to black (Color ID 26)
  • Color missing from secondary brick geo is handled correctly
• Overwrite Scene Option:
  • Delete all objects and collections from Blender scene before importing.
