Please consider replacing 'digits' library

Hi @jgm, happy new year!

typst depends on digits, which seems to be unmaintained (the last upload of digits was ~8 years ago, and the code repository doesn't exist anymore).

I noticed this since we are about to package typst for Debian, and we need to package digits as well. This is not a blocker, but I thought it would be good to let you now.

I've done this.
