processNbtMessage

This method is internally called by fromNotch.

mcpc 1.20.3 uses NBT instead of JSON in some places to store chat, so the schema is a bit different. processNbtMessage normalizes the JS object obtained from nbt derealization to the old JSON schema, so it can be used to instantiate a ChatMessage.
