Kawrakow 910a134094 IQ2_KS: 2.1875 bpw non-linear quantization (#85) ...

* Experimenting

* iq2k: Try make_qx_quants for the scale

Slightly better for LLaMA-3.1, Gemma-2, slightly worse for
Qwen2.5

* iq2k with make_qx_quants: adjust scale

* iq2ks: basics

* iq2_ks: CUDA works

* iq2_ks: WIP

* iq2_ks: WIP

* iq2_ks: Zen4

* iq2_ks: AVX2

* iq2_ks: scalar dot product

* iq2_ks: ARM_NEON

* iq2_ks: Metal

* iq2_ks: faster Metal

LLaMA-3.1-8B:
PP-512 = 475.22 ± 0.37 t/s
TG-128 =  45.32 ± 0.03 t/s
