Add SL(4), based on fork by @LimHyungTae, here: https://github.com/MIT-SPARK/gtsam_with_sl4

I made a bunch of changes to leverage LieGroup and MatrixLieGroup, added unit test, and converted the python example to a notebook.

Hallo Frank, thanks for taking your time. I'll take a closer look as well by the end of this week!

@LimHyungTae any comments before I merge? After I merge you should in principle be able to abandon your fork and just run VGGT-SLAM after pip install gtsam-develop, a new package that provides bleeding-edge access.

I'll merge now, so @LimHyungTae can test whether pip install gtsam-develop does indeed work with VGGT-SLAM

Thanks, @dellaert, everything looks good to me (and the captured figure is VGGT-SLAM with gtsam-develop). Next time, I'll follow your guide and refer to this PR ;).
