Q4_K_R4 (#129)
* Something is still wrong
* Simply don't see what is wrong
* q4_k_r4: finally works on Zen4
I had forgotten to prevent token_embd.weight being quantized
with q4_k_r4!
* q4_k_r4: AVX2
We get PP-512(LLaMA-3.1-8B) = 267 t/s on a Ryzen-5975WX.
This is ~30% better than Q4_K_S.
* q4_k_r4: NEON
We get PP-512(LLaMA-3.1-8B) = 110 t/s.
Not quite as good as q4_0_r4, but still a massive
improvement compared to he 69 t/s for q4_K.
* q4_k_r4: slightly better AVX2
PP-512 goes from 267 t/s to 282 t/s on Ryzen-5975WX
* Minor
* Minor
