Enhancement: Add support for multiple Textual Inversions versions

[metapea]

based on #218:
Just like with loras in civitai, there can be multiple Textual Inversions in one page.
So adding support for picking which Textual Inversion or version would needed, since i have no idea what Textual Inversion artbot choose from a page with multiple Textual Inversions.

Same answer here as #221
I'm on your side with this one, there's too many embeddings that are listed as versions on Civitai.

This is a lot of work actually. Only reason I did it with loras is due to the LCM versions matching different samplers.
