Typst target

[lua-vr]

Should be possible to support given https://github.com/jgm/typst-hs, but I'm not sure.
It's on Hackage already: https://hackage.haskell.org/package/typst

[lua-vr]

Note to self: I need to add some default expansions that allow writing lists, tables and the likes to Pandoc, and this will also apply to Typst. Right now it's impossible to write them because of the lack of attributes for list items or table cells/rows.
