I often want to quantize with --pure to see quantization performance without quantization mixes. But for models where there qre tensors with row sizes that are not multiple of 256, this results in a crash for k- and i-quants. Hence, lets add a check if the quant selected via --pure is applicable, and change it if not.

ffn_down_expsrow sizes are not a multiple of 256 in DeepSeek-Lite. When using--purewithllama-quantizethis leads to a crash. I got tired of having to do custom quantization overrides in that case, so this PR adds the check for divisibility by the quantization block size also for--pure, and uses the fallback quantization type if necessary.
