Nipple Pull - Pierced / Chained / Clamped

Wasn't satisfied with the other nipple pull LoRAs, tried my hand.

Works well with base Pony and Pony Realism.

Does not play well with my Extra Breasts LoRAs, though 4 and 3 breasts work sometimes. Will probably also struggle with LoRAs that majorly modify breasts.

The directional controls do not seem to work at all, except 'up_yank' works a bit and 'breasts apart' works pretty well; unfortunately I think that's mostly due to dataset limitations, it was hard to find enough of some poses of good enough quality to include.
