Background

To make the conversations with the bot more reader-friendly, this PR aims to integrate document production using typst, a modern alternative to LaTeX. Typst is a new but robust document scripting language capable of:

• generating text
• creating figures and graphs
• representing images
• formatting text (lists, paragraphs, sections, etc.)
• using complex mathematical symbols (integrals, sums, etc.)

Working changes are early but the current goal is to have a pdf document that is updated every question interval.

Changes

Adding tools for converting .log content into .typ files and the necessary libraries for compiling to a pdf.
