Create an operator to detect lewd images using Bumble's private detector

[dennyabrain]

Bumble has open sourced their lewd detector - https://github.com/bumble-tech/private-detector
This is a pretrained model that can flag nudity in images it seems. As part of this issue, lets try to create a feluda operator to integrate this. Additionally we can consider supporting videos as well. Where we sample frames using techniques used in other video operators and run them through their model.

This operator could help solve #364 as well.
