Rare tokens finder

[CodeExplode]

Hi all,

I've made a simple extension for webui to generate rare tokens which can be used for finetuning/dreambooth, trying to generate unlikely words which shouldn't conflict with anything else (e.g. 'sks' already exists in stable diffusion as a gun and so using it for training often causes guns to show up in the final images).
