Re-implement value noise

[aksiome]

Here is a link to the previous implementation of value noise for reference: https://github.com/SBtree-bit/Bookshelf/blob/93273ea04f6e3dd8eec37cf488a9f50e78155f95/datapacks/Bookshelf/data/bs.random/function/noise/value_noise/yloop.mcfunction

For now simplex noise yields better performances but I'm sure value noise could be improved. If we want to generate fractal noise (noise with multiple frequencies and octaves) we'll have to use the most performant of the 2 (we'll also have to test if value noise with multiple octaves reduce grid-like artifacts to an acceptable degree)
