Q6_K_R4 (#130)

Browse Source 
* Adding q6_k_r4

* q6_k_r4: 1st functional AVX2 version

* q6_k_r4: AVX2 and simple Zen4

"Simple" as in processing 4 instead of 8 rows at once.
On Zen4 we get PP-512(LLaMA-3.1-8B) = 238.3 t/s vs
195.2 t/s for Q6_K. TG-128 @ 1 thread is 7.94 t/s
vs 5.38 t/s for Q6_K.

* q6_k_r4: 1st NEON version

PP-512(LLaMA-3.1-8B) = 78 t/s vs 57.6 t/s for q6_K.
TG-128 is slightly lower rthan q6_K for low number of threads,
becomes very slightly better at 8 threads.

* q6_k_r4: slightly faster NEON

PP-512(LLaMA-3.1-8B) = 83.25 t/s

* q6_k_r4: slightly faster Zen4

238.3 t/s -> 243.2 t/s
