This patch adds quanto KV cache quantization support for Transformers. The placement is unfortunately a little awkward, but we need to pass the same
QuantizedCacheobject to each step. Happy to put it somewhere else.Also, added optimum-quanto to requirements.txt. It can probably be safely made an optional dependency, but it's quite small and I believe portable across platforms.
