[Feature Request]: Support Binary Quantisation

### Describe the problem

I would like to have support of binary quantisation in Chroma DB.

### Describe the proposed solution

Maybe a simple feature flag or argument to support quantisation when adding docs to the collection.

### Alternatives considered

_No response_

### Importance

would make my life easier

### Additional Information

https://huggingface.co/blog/embedding-quantization

Start by reading the issue's proposed feature-flag or argument idea and the linked Hugging Face article on embedding quantization. The payload names no files, tests, or entry points, so first locate Chroma's collection-add and embedding storage paths. Done means an agreed binary-quantization design is implemented and verified with coverage for quantized additions and retrieval.
