Trailing underscore in output file names. Why?

Title.

ComfyUI/nodes.py

Line 1284 in cfe1c54

file = f"{filename}_{counter:05}_.png"

There originally was something else after the counter but I removed it and left the _ because I was planning on adding something else there.

I would suggest for both underscores to be conditional, and a prefix/suffix setup be done for the file names. I'm not familiar with what Python has for built-in functions, but an underscore-separated merge from array to string is what I'd use in other languages. This would also allow for a more configurable naming structure from the user's end if the necessary fields were added to the node.
