[electrophysiology_browser] On-demand file download tarring

[MaximeBICMTL]

Alternative to #10411

Description

This PR makes two changes;

• Replace the download links in the electrophysiology browser to use the LORIS API instead of get_file.php.
• Add a new ArchiveStream class to LORIS core to tar on-demand a file or directory and make it available to download. This new class is adopted in the electrophysiology browser to make it possible to download CTF directories for MEG.

Since this approach request came from @driusan I guess I am gonna assign this to you. I tested it locally (of course) but feel free to re-assign it if you prefer.

Most of these endpoints don't work, like /bidsfiles/channels, for example.

The issue was not introduced by this PR but it makes this switch problematic.

This join is responsible for the channels, picked as an example, and channels works for me If I change that line to:

LEFT JOIN physiological_channel pc
ON (pc.PhysiologicalFileID = f.PhysiologicalFileID)

and add this at the end, to similarly obtain one:
GROUP BY pc.PhysiologicalFileID

I didn't look too deeply into why this is the case, but that query can use some love.

That query in the DB returns NULL for everything except filelocation and archive_file_path, prior to my change, which returns the channel_file_path

lmk if you can't reproduce it

Oh, good catch @jeffersoncasimir, I did not run into that issue during my original tests, but after looking at your explanation and doing more tests, I can reproduce.

I think the problem is that the join subqueries use LIMIT 1 before the join, so if the first entry of each table matches the acquisition file you are in luck (which I guess was the case in my original tests), and in all other cases the query is broken. I changed the query to use subqueries rather than a join, and use a where condition to get the correct entries.

I rebased on 29-release and added a commit to fix the query, it fixed it for me, tell me if you are still having issues.

Works great!
