shrink the IN dim respect to the SIMD

[huoyushequ]

the SIMD_8 is used in the method matvec of QLinear, so the input x with (B,IN) should transformed into [[Simd<f32, 8>; B]; IN/8]

[huoyushequ]

change from [[Simd<f32, 8>; B]; IN] to [[Simd<f32, 8>; B]; IN/8] can greatly reduce the stack usage and slightly enhance the reference speed.

This is a good change, does it impact speed?

I was considering adding a rust gated feature that lets you do generic constant arithmetic, but this solution is probably better for now.

[huoyushequ]

i tried the `#![feature(generic_const_exprs)]

![allow(incomplete_features)]`

but it generates a bunch of warnings. On my desktop, the speed changed from achieved tok/s: 4.8163757 to achieved tok/s: 5.0361977

sorry! I'll get this checked in. just made a bunch of other changes that I need to merge in.

this proj is a great place to learn rust and llama and cuda(triton), very appreciated, hope to do something helpful to the proj

Would love any contribution, I'm also learning Rust and Triton on the fly.

What if we try this library? It seems pretty cool. https://docs.rs/typenum/latest/typenum/

Another idea would be to explore adding testing. Not sure how unit tests work in rust, but it would be nice to have these for small sizes.

import of the typenum would unnecessarily complicates the repo and make the code unintuitive just to bypass the limit of generic_const_expr

I am happy to write some unit test after i carefully finish the reading source code
