No speaker note support for custom page sizes

[joelvonrotz]

Hello,
I usually like to create 3:2 for technical presentations, which perfectly fits for some of the diagrams I show. I noticed, while adapting my own theme from the simple-theme, that speaker notes are only supported for specific formats (presentation-16-9 and presentation-4-3).

I don't think it's needed. The following snippet from core.typ has been commented to test if it works with a slide size of 24cm x 16cm (3:2) and it works without any issues. Is the assert really needed?

assert(
  self.page.paper == "presentation-16-9" or self.page.paper == "presentation-4-3",
  message: "The paper of page should be presentation-16-9 or presentation-4-3",
)

What are your thoughts on removing this assert?
I might as have missed something big, so please correct me if I wrongly interpreted this.

I have just looked at the code and found that it really hard-codes the width/height of the "only possible" two paper sizes in a few places related to the speaker notes feature. I was also surprised by that and would like to see support for arbitrary page sizes. (E.g., I am trying to convert a certain corporate identity style from Powerpoint, which is also 16:9 but uses a different page size.)
