Store Image and Embedding Without Subject

[barrycarey]

Is your feature request related to a problem? Please describe. I'm looking to store embeddings without a specific subject.

Describe the solution you'd like An API Endpoint to add an image and embedding without a subject. From what I see in the docs and code, the subject is currently required even though the column is nullable.

Describe alternatives you've considered Manually saving the image and embeddings.

Additional context The goal is to be able to search a given image against previously saved unknown faces.
