Add Hebo

Migration of the HEBO algorithm from a plugin repo on GitHub into the Orion repo.

LGTM. There may be 2 comments worth creating issues, the other one is only a minor fix.

If you move the hebo tests to the long/ folder you can add hebo to the test-long matrix CI job and it will run hebo in parallel to the unit tests. You might also increase the max-parallel job in the test-long CI so make sure all the test-long run in parallel

HEBO tests take a significant amount of time to run, so it should be moved in long folder and run in the test-long matrix as pointed out by @Delaunay .

@bouthilx agreed! I moved the tests to the "long" folder, which I then renamed to "extras". (I also adjusted the workflow names to reflect this).
I suggest we place all tests related to algos that are installed through extras-require in that folder, regardless of how quick they run.

This seems good to go on my end. Lmk if you have any comments (@Delaunay as well).

Oops, I forgot to increase the max parallel jobs value (as suggested by @Delaunay ) I'll do that now

I disagree. The number of algorithms will continue growing and this will increase significantly the number of jobs. I believe we should try to reduce the number of jobs, and the criterion to do so is whether the algorithm takes to much time to run sequentially or not.
