- improve BMe extractor with new added classes.
- I have written a half of BME validator, but I gave up now.
* it takes too much time and I don't want to pay more on it. postpone it to next update.
* I annotate all of BMe validator code for future implementation.
* the improvement of BME json files (upgrade them to YAML format) also is postponed.
- change some interface in common.py. synchronize it to other modules using it.
- update blender_manifest.toml to the latest version and fix the issues raised by blender when packaging.
- use blender do packaging work. remove redist.py because blender_manifest.toml has gitignore like filter feature when packaging.
- update document about installing, configurating, building plugin for blender 4.2.
- update a document image for blender 4.2.
