[DOOM] Universal Completion Reward

Heavily inspired by Dusted's Pandemonia, and in fact, most of the code were taken straight from the mod itself lol, but was reworked in the way that behaves a bit differently from the original.

Why making this you may ask? Simple answer really, as there were attempts for this concept but most of them either had their projects completely abandoned or just wasn't good nor polished in general like Pandemonia does, not to mention there were pretty much zero beneficial reason of why you want to 100% everything on the map in a casual run other than being a completionist, and this is where I get to crack my knuckles and start going ham with it.

Shoutout to Kicked-in-Teeth for their dice sprites, as the project would've make things a bit harder without it.

[Current Features]

- Upon killing all enemies on the map or found all the secrets, you were given a dice as a reward instead of a white gem in Pandemonia.

- When rolling the dice you were expectedly given a random number, and these numbers aren't just there for doomcute detail, as there are different tiers of rewards represented by those said numbers, with 6 being the lowest and 1 being the highest, worry not much though, as chances of getting all these tiers were all equally 50/50, so getting 1 is just as possible as getting something like 5 or 6, as well as having rewards just decent enough that it doesn't feel like a complete waste of time even you got shit tier.

- However, this also means you can only carry 4 over the course of each levels.

- A little customize menu that allows very specific pickups spawn at certain tiers.

- Like the title suggests, this works with any mods that replaces either weapons, items and powerups or all of the above.

[Current Known Issues]
- Thrown dice straight up no-clips into the backrooms if the floor is consists of skybox, so be considerate where you're throwing for now.
