Better Random

Or Better PRNG, is a mod which replace Minecraft's default Linear congruential generator (LCG for short, used for generating most of random game events) and Xoshiro128PlusPlus (used to generate "sequences" aka random generator used for LootPools) with a better random number generator, gjrand.

Features:

• Replaces RandomSupport#create, and subsequently, Entity#random, Level#random, countless other places including mods;
• Replaces RandomSequence and RandomSequences with versions which use gjrand;
• Replaces Level#getBlockRandomPos to use Level#random. Previously, getBlockRandomPos utilized LCG with even worse properties than one of Level#random.

Compatibility:

Should be compatible with everything that doesn't go around public interfaces vanilla code provide. Existing RandomSequence saved data is left untouched (in meaning that nothing is done to it through code, but Minecraft continue to load/create it upon server start), and removing Better Random mid-game won't have any side effects.
