add custom line numbers

[JL710]

This PR allows to pass a function that takes a line number and returns content to the line-numbers parameter. Thus allowing users to style the line numbers as they wish.

Example

#import "algorithmic.typ"

#import algorithmic: algorithm-figure, style-algorithm
#show: style-algorithm
#algorithm-figure(
  "Binary Search",
  vstroke: .5pt + luma(200),
  line-numbers: number => str(number),
  {
    import algorithmic: *
    Procedure(
      "Binary-Search",
      ("A", "n", "v"),
      {
        Comment[Initialize the search range]
        Assign[$l$][$1$]
        Assign[$r$][$n$]
        LineBreak
        While(
          $l <= r$,
          {
            Assign([mid], FnInline[floor][$(l + r) / 2$])
            IfElseChain(
              $A ["mid"] < v$,
              {
                Assign[$l$][$"mid" + 1$]
              },
              [$A ["mid"] > v$],
              {
                Assign[$r$][$"mid" - 1$]
              },
              Return[mid],
            )
          },
        )
        Return[*null*]
      },
    )
  },
)

Hi @JL710, thanks for the patch. Can you add a test, corresponding documentation to the README please? The added info should be copied into the NEWS.md as well.

@quachpas I added/updated a unittest and added documentation. Since I never worked with tytantic before I tried my best with the unittest. You might want to special check the unittest changes.

Thanks, that's perfectly fine I'll check it on my side

I've reviewed the patch. Thank you, it looks nice and I'll be glad to merge this ! I've left comments in the PR for you to look at.

Thank you! I've reviewed the new changes, and that should be the final review. After this, I will merge this.
