[Feature request] Custom name & color for stem

[MacTheZazou]

I would like to customize the name & color of the different stem, is it possible? My goal is to include the key of each stem by running libkeyfinder from mixxxdj just after stem separation. I can modify the code myself to include libkeyfinder, but can't find a way for custom naming & Would find nice to set custom color to the different stem with hex cli option.

You just need to edit the metadata.json file

You can do this programmatically by using the create_metadata_json function in metadata.py.

Closing this issue as I'm not planning to add this as a CLI option.
