Add typst support to typewriter.

Is your feature request related to a problem? Please describe.
I like the option that rnote allow creating documents combining text input imported pictures and handwritten notes.
But sometimes I also would like to write mathematical formula or formatted text by using the typewriter.
Typst should be a nice solution for this, because the syntax is powerful and still very simple.

Describe the solution you'd like
An option to enable typst can be added at this menu.

For this the typst crate, which does also provide a lib, can be used.
The disadvantage of this is that the typst is currently not published at cartes.io, which would also block rnote releases on crates.io.

Describe alternatives you've considered
Write hard to read formula with hand.
