Refactor in several libs to make this smaller and easier to reason about

[rom1504]

Initially this repo was about integrating multiple small components into a simple retrieval system it now growed a lot and got a lot more features and it's becoming too big

to grow in a reasonable way, let's extract big components in smaller libs and use them here:

• [ ] clip inference
• [ ] clip back
• [ ] clip filter
• [x] all-clip

should be independent libs

img2dataset and autofaiss are already independent

[rom1504]

Now even more important with clip client has it wouldn't need much dependencies at all if it was its own module

i might tinker with this refactor
