Switch to Pest

Closes #1 and Closes #2.
Error reporting needs improvement.
I was thinking maybe we could use miette for error reporting and I noticed there is an open PR for miette support on pest.
I think it would be interesting to explore miette for error reporting. Let me know what you think. I'd love to work on the open PR.

Upstreaming miette support to pest would be great!

@prsabahrami could you please revert the changed formatting settings and put them in a follow-up PR? All the unrelated changes make this a bit hard to review.

Fair enough :))
Done.

Couldn't agree more.
I'll start looking into it.

Looks good to me, thanks a lot @prsabahrami!

Also, pest is really cool, especially the online playground.
