TrakPlayer mod for Doom

Reads the TRAKINFO lump and plays the appropriate music. This makes the extras.wad remixed soundtrack from "DOOM + DOOM II" work on ZDoom.
The mod adds a new item in the sound options to switch between the loaded soundtracks (requires to change level to take effect).
(This is my first ZScript mod, pls spare me)

Dev info:

The TRAKINFO lump is just a JSON file that specifies music replacements. This is how it looks like:

{
 // SHA1 of D_INTRO lump
 "0c0acce45130bab935d2f1e85664b29a3c724fcd":
 {
  // set O_INTRO as replacement when selecting the "MIDI" soundtrack
  "MIDI": "O_INTRO",
  
  // set H_INTRO as replacement when selecting the "Remixed" soundtrack
  "Remixed": "H_INTRO"
 },
 // ...
}

The mod will automatically add new soundtrack types to the option menu, so if your mod adds new music replacements under the name of "CustomRemixes" they will automatically be available in the sound settings.
You can find a list of SHA1 hashes for Doom music here.
