Description

# Add multi-modal loss

As discussed in #249, adding the loss function as described in [CLIP](https://arxiv.org/pdf/2103.00020.pdf) would enable users to work with multi-modal datasets.

The pseudo-code (from the paper) is:

Research direction

Start with the discussion in issue #249 and the linked CLIP paper, since no implementation file, test, or entry point is identified here. Define the loss behavior for multi-modal datasets from the paper's pseudocode, then verify that the resulting implementation supports the intended user workflow.
