Set a cron job to run extended testing

What would you like to see added in this software?

Following #35 (comment) the bold_realignment.ipynb is excluded from CI testing so that merging PRs is not delayed by slow processes.

A weekly cron job should be set to ensure that the bold_realignment.ipynb notebook runs without issues.

This will require re-working the notebook detection script:
https://github.com/nipreps/nifreeze/pull/35/files#diff-7aed50a8017e9faa15e5893ce4c5176c2aafc6f4a4b72a2bcc317e4f59fabc05R31

Alternatively, a new ismrm_sample_subset.txt could be created with a subset of the datasets listed in the original ismrm_sample.txt file, and a flag be added to the notebook so that the subset is used by default and gets tested by default, leaving the larger set to the cron job.

Do you have any interest in helping implement the feature?

Yes

Related to this, a cron job was added in PR #169. Now we just need to fix the notebook (x-ref #117 (comment)) and make the extended testing be run only e.g. once a week.
