Numbers outside margin

[pmudry]

A first implementation in the direction of #53

Two shortcomings with the current implementation :

• radius is not implemented as only the whole block can have a radius and not the grid element themselves. I don't see any elegant solution to solve this currently.
• when skipping line numbers, the width is not completely taken into account. The logic behind the skipping is not 100% clear to me.

I don't have time to do a full review (yet) since I'm working, but I see two main pointer:

• There's a bash file for running tests which is not needed, and must be removed, I use typst-test by tinger
• There's a lib_back.typ which you have to remove too, we use git to avoid needing backups :D

Otherwise, it looks good from the quick look I've had it looks good and simpler than I expected, I'll play around with it as soon as I have time for it. Thanks a lot for your work!

I had no clue something such as typst-test existed, it's really nice! I integrated a new test for the new numbers-outside-margin option.

Sorry for dangling backup file. It has been removed.
