[Feature Request] STSP and LTSP Samplers

[saphtea]

Hey! Would love to see these two samplers implemented into the comfyui addon for Disco Diffusion.

They were implemented into the DD notebook in the pull request here alembics/disco-diffusion#181

Running this version of the notebook I have gotten faster rendering times in general due to less steps needed for a coherent generation. Using it it seems like it speeds up the generation itself, but I haven't tested at all if that's objectively the case.

Oh nevermind, it's already implemented, because you made the original codebase for these samplers in DD lmfao. Thank you for your work seriously!!
