STYLE: Fix registration process id string floating point formatting

[jhlegarreta]

Fix formatting of numbers that can be floats when creating the registration process id string: when transitioning to f-strings (commit ac6040f), it was assumed that sigma and grid_resolution would be integers, based on the existing formatting. However, these attributes can be set to non-integer values. The pre-f-string transition solution, e.g.:

"(...)_sigma_%03d_grid_%03d" % (subject_idx, iteration_count, sigma, grid_resolution)

trimmed the decimal part, and thus, for e.g. sigma 7.5 and grid_resolution 1.5, it would produce:

'(...)_sigma_007_grid_001'

With the introduction of f-strings, i.e.

f"(...)_sigma_{sigma:03d}_grid_{grid_resolution:03d}"

this would produce an error, since the sigma and grid_resolution floating point value cannot be formatted as an integer:

{ValueError}ValueError("Unknown format code 'd' for object of type
'float'")

This patch set fixes the error by adopting the previous behavior: it trims the decimal part.

Left behind in commit d7c6bd8.
