♻️ DRY "Gathering the output file paths from" in cpac_group_runner

[shnizzedy]

Not for this PR, but

C-PAC/CPAC/pipeline/cpac_group_runner.py

Lines 178 to 191 in 25ea215

	# remove any extra /'s
	pipeline_output_folder = pipeline_output_folder.rstrip("/")
	logger.info(
	"\n\nGathering the output file paths from %s...", pipeline_output_folder
	)
	# this is just to keep the fsl feat config file derivative_list entries
	# nice and lean
	dirs_to_grab = []
	for derivative_name in derivative_list:
	for resource_name in resource_list:
	if resource_name in derivative_name:
	dirs_to_grab.append(derivative_name)

and

C-PAC/CPAC/pipeline/cpac_group_runner.py

Lines 394 to 407 in 25ea215

	# remove any extra /'s
	pipeline_output_folder = pipeline_output_folder.rstrip("/")
	logger.info(
	"\n\nGathering the output file paths from %s...", pipeline_output_folder
	)
	# this is just to keep the fsl feat config file derivatives entries
	# nice and lean
	search_dirs = []
	for derivative_name in derivatives:
	for resource_name in resource_list:
	if resource_name in derivative_name:
	search_dirs.append(derivative_name)

could be DRY'd into a single function
