Feature: seed repeat

[vsp245]

@adieyal
This is a great extension, thank you very much.

Could you please add a small feature to the interface: “Repeat the seed a certain number of times.”

Maybe add something like this to the "helpers.py" in the "get_seeds()" function:
all_seeds = [seed + i//_rep for i in range(num_seeds)]

To receive a list of seeds of this kind:
#_rep = 3, num_seeds=7
[321001, 321001, 321001, 321002, 321002, 321002, 321003]

This can be useful to see how the same seed looks with different variables in the prompt, or for more targeted experiments with [Cyclical Sampler] in batch processing.
