Swap out slidev for some rust-based tool

[hdoordt]

Currently, modmod builds a NodeJS package that uses Slidev to create slideshows out of markdown files. Being a Rust course, it would be nice to depend only on Rust-based tooling, and therefore swap out Slidev for something Rust based.

What we need in a tool:

• Convert Markdown slides to slideshow
• Include Markdown files in other Mardown files
• Support custom themes
• Be open source (MIT Licensed)
• Support presenter mode
• Render to HTML

List of tools that may or may not support the features we want:
