Feature: Move Python dependencies into extras

[ashvardanian]

Describe what you are looking for

Pillow and NumPy aren't as heavy as PyTorch, but it would be nice to move those into a list of optional dependencies.

Moreover, Pillow often causes version conflicts with other packages installed on the system. I've just noticed that in a USearch+StreamLit demo, where UCall comes as a dependency. We can have some custom annotation classes in UCall to mark pil.Image or np.ndarray arguments without explicitly importing them. On a related note, TenPack will be getting some useful functionality for tensors packaging and media parsing, that may come handy here.
