Feature request

The current Chroma class has add_images method which takes uris: List[str] as parameter.
It will be helpful if there will be an operation that takes b64_texts as parameter instead of the uris.

In most use cases, the images are extracted from pdf files as b64 so no uri available to pass to the add image method of Chroma.

If there is a way around, please suggest. It would not be optimal to save the b64 images to file first in order to pass the uri.

Thanks,
Marcelo

Motivation

In most use cases, the images are extracted from pdf files as b64 so no uri available to pass to the add image method of Chroma.

Proposal (If applicable)

Just add another method that takes base64 text as input instead of uris
