Minor patches

• Dynamic prompt length checking.
• Change split to regex.
• Allow seeding, seed function made by Zippy, untested on stable-diffusion model, but preliminary heuristics via glide on https://github.com/spuuntries/simulakekbot/tree/imagen passes fine. Presuming inference pipeline is identical to latent, this should work fine.
• Prefix cond_scale to filename.
