Decouple cheats from ROM file/folder structure

Description

As is, with the current way cheats are handled, they're specific to your own file and folder structure (in other words how your ROMs are named and where you put them)

This makes it impossible for somebody to create a cheat pack that anybody can download and use.

Release Context

Release V0.3.1

How to solve the problem

It would be better if the cheat file/folder structure was decoupled from ROM names but instead used the ROM header similar to how metadata (boxart) works and to how emulators do it.

That would allow people to create cheat packs that anybody can use, which is currently impossible, instead of requiring a lot of manual work for each user to create cheat lists for all their games.

Describe alternatives you've considered

I have considered writing my own application to read each ROM header and generate cheat list .txt files for each of them, but obviously this is not as clean of a solution as being able to have a universal cheat pack that "just works".

I may do this for the short term, but in the long term it would be more ideal to decouple cheats from the ROM filenames.
