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
