support compressed disc's in the form of .chd

This would need to be a change made in the main jak-project project, not here.

However I'm not convinced it would actually be a good one. Emulators are a different scenario, the ISOs are the only input for playing the game.

For OpenGOAL, the ISO is just the easiest way for the user to provide the files for the tools to use. The ISO is fully extracted to disc, eliminating any benefits of better compression. Not the mention the fact that CHD would be another dependency we'd have to integrate with -- but with no real tangible benefit.

The only benefit i can see is for users that have fully converted their libraries from ISO to CHD to save space. However in this case, there are tools to convert back temporarily -- as well as the launcher will soon support installing from a folder, and tools like 7zip can be used to extract a CHD file.
