Tested against modified babric intermediaries and it works flawlessly.

I've externalized the code defining source namespace to game provider. I took a different approach to fix the 'hole' issue, I'm creating a new mapping with the source namespace set...

I'll wait for the next TR release before updating the code accordingly.

I've updated TR to take advantage of FabricMC/tiny-remapper#128. Should `TinyRemapperMappingsHelper` be removed as it is fully replaced by TR `TinyUtils`?

It takes quite a lot of time and efforts to do. Only doing 1.3.2 took me at least 2 weeks of really intense work, only working on it during all...
