Refactor the codebase to the updated simdeez API

[arduano]

Leaving this issue here to track the fact that I'm working on it, let me know if that would conflict with anything

[arduano]

An example of how the new API looks like would be here:
master...arduano:rust-simd-noise:master
currently in the cell_32 file.

@verpeteren This may create some pretty nasty merge conflicts, should I wait for any of your other tasks to be finished before continuing?

Oh and also, I've added Arm Neon support to simdeez in that new version and I'm planning to add wasm as well, so the library would be able to support those too.
