Change Default PRNG

[IgneousRed]

Some time ago I mentioned in the discord server about how bad the default PRNG is.

It is inspired by PCG, but I could not find the exact copy.
If it exists I would like to see it, but I don't think the creator made this one.

Testing with one of the best libraries, it fails quickly.
The PRNG fails after 2^19 bytes on the most stringent test.
I would not recommend any 64bit PRNG that fails before 2^45 bytes.

Better alternatives exist, in randomness, predictability and speed at the same time.
I would recommend MWCP64, I think it is a great choice for Odin (for modern hardware).

For more info, I made a repository with relevant data.
https://github.com/IgneousRed/PrngBoard (Repo was private, fixed)

I would really like for my favourite language to have a good PRNG.
Feel free to ask anything :)

Thanks for reporting this. We've known about it internally but haven't decided on a path forward. We'll keep the issue here to track progress.
