refactor(structure): merge infer dir into rvc for move uniform API access

[alexlnkp]

this also moves train from infer.lib to rvc.lib which just makes more sense than having train under infer

might be too extreme of a change for now, but hopefully not, since this tidies up the structure quite drastically

i guess i could preserve the split of train and infer by making dirs that contain scripts that either one needs, not sure if this would be necessary though... but i'm up to making changes!

Well, don't be so hurry 😂. I'm moving the infer to rvc gradually, by viewing the codes line by line and place them into the proper position to modularize it. Now, just keep the half-infer half-rvc status and the infer part will decrease, the rvc part will increase.

[alexlnkp]

Yeah, sorry, I'm quite hasty when it comes to making some changes which I planned to do for months 😅
I thought it'd be easier to first move things in their new places and then start making changes about how these things are used, but I guess that is not always the case...
Should i close this PR?

Move many stuffs at the same time will make it easier to ignore some codes refer to it.

Yes, you should. But thanks to your passion. If you like, you can separate the uvr5_park part first, which will not be included in the rvc folder.

Alrighty then :)
