Rename MTS suffix

[sandrinebedard]

Description

This PR addresses #116 . It renames all MTS files to be BIDS compatible:

acq-MTon_MTS → flip-1_mt-on_MTS
acq-MToff_MTS → flip-1_mt-off_MTS
acq-T1w_MTS → flip-2_mt-off_MTS

The change itself looks good (that is, it looks like you correctly renamed all the files). The Dataset Validator check is failing, though. I re-ran it several times because of some transient issues (scikit-learn versus sklearn in some dependency, temporary network problem while downloading from amazon), but this run looks like it's an actual issue:

sg_params_checker -path-in ./
Traceback (most recent call last):
  File "/opt/hostedtoolcache/Python/3.7.15/x64/bin/sg_params_checker", line 11, in <module>
    load_entry_point('spinegeneric==2.5.dev0', 'console_scripts', 'sg_params_checker')()
  File "/opt/hostedtoolcache/Python/3.7.15/x64/lib/python3.7/site-packages/spinegeneric/cli/params_checker.py", line 86, in main
    MTS_acq = item.filename.split("_acq-")[1].split(".")[0]
IndexError: list index out of range

It looks like the params_checker is using the old filename format. I'll make a (backwards-compatible) fix upstream and re-run the Dataset Validator check for this PR after.

Once I can get the Dataset Validator check to pass, this looks like it can be merged.

Is there any update on this problem? Thanks!

Sorry, I haven't had time to work on fixing the Dataset Validator. But:

• I've looked into it enough to see that this is because of various bugs in the Dataset Validator, which will take some time to fix; and
• Clearly just renaming the files should not affect the things that the Dataset Validator is supposed to be checking anyway.

So, I'll override the check and merge this change now, and open a separate issue for fixing the Dataset Validator.
