[Issue]: Stylized progress bar for all samplers

[diniamo]

Issue Description

The only sampler that has a stylized progress bar (console) is UniPC, and it's also the only one I could find the code of. If this is not something that anyone wants to work on, can I at least have a pointer as to where the progress bar logic is handled?

On an unrelated note, why is UniPC the default sampler in SD.Next? I couldn't find any information on that.

Version Platform Description

Version: 926b866
Arch Linux, Kitty terminal (also happens to my friend who uses Windows Terminal)

all other samplers come from external code, either compvis (ddim and plms) or k-diffusers (all others). modifying progress bar would be trivial, but that would mean that code would not be in sync with upstream and no automatic updates would be possible.

unipc is the only diffuser that is natively built inside this repo, so i can do those enhancements.
why is it default? because its not bad and its really fast. something has to be default, so why not unipc?

and why is this created as an issue? its a valid question, but far better suited for discussions.

That's because I didn't know Github discussions existed, thank you for pointing that out and for your answer.
