Description

Add integration tests for EEG BIDS import.

For the tests to pass, this PR requires to add the Face13 BIDS dataset to the test S3 bucket as incoming/Face13. Only the sub-OTT166 subject is required, the participants.tsv file should contain this:

participant_id	cohort	site	project
sub-OTT166	Fresh	OTT	PUMP

This PR also adds the ability to use project aliases when using --createsession in the current BIDS importer to be consistent with the new BIDS importer.

Description 2

Since the tests did not work at first, I also added a bugfix in this PR to make the code work with the most recent mne version (1.11.0). Note that the code no longer works with the previous version (1.10.x or less).

@jeffersoncasimir I added two commits to this PR:

• 935e4df reworks the check_file_tree test function into assert_files_exist as the former had terrible debugging ergonomics when it was failing.
• 37e28d6 updates the arguments of mne_edf._get_info() to account for the latest mne update two days ago that changed the signature of this function (which is why your second run failed).
