Markdown / rich rendering (with streaming)

[gianlucatruda]

Ideally, I'd love something like https://github.com/Textualize/rich that:

• Renders markdown reliably
• Supports streaming
• Supports syntax highlighting for code snippets

There doesn't seem to be a Rust equivalent yet. Just a lot of people seeing the need for that and some very early undocumented work.

https://crates.io/crates/aio-cli/ seems to be achieving some of the things I'd like, but AFAICT it's just using a custom, homerolled formatting system

https://crates.io/crates/tui-markdown might be a step in the right direction, but I'd probably have to roll a lot of my own streaming support.
