Write a rootcause book

[TethysSvensson]

I want to write a small introductory book and put it on the domain rootcause.rs. I want it to be similar in scope to https://serde.rs.

Hi there! I’m a regular user of rootcause, and I just wanted to say thank you for such a fantastic library—it’s truly amazing. I was reading an article about error handling today, and although it was promoting the exn library, I realized its core philosophy is very similar to rootcause. I thought it might be a helpful reference for you while you're writing the book. I’m really looking forward to it and can’t wait to see it!
