Introducing estampa: Minimalist server for the Misfin protocol

Hi everyone! I've been working on a new server for the Misfin protocol in Rust, using Tokio and rustls. It's called estampa, and it aims to be a rather minimal implementation of the protocol. In other words, its main purpose is pretty much only recieving and storing Misfin messages.

For now, the only way to read messages will be through the filesystem, but in the future I plan to implement GMAP and gembox support, so clients can also connect to it and fetch their messages (perhaps even maybe within a separate piece of software, kind of like how Dovecot-Postfix works)

It's also important to note that the server only implements Misfin(B) for now, but Misfin(C) is high on my list of priorities for a future release.

Let me know what y'all think! I'm open to feedback, and I'm well aware that there's a lot of room for improvement, but if y'all have any notes on what I could improve on, I'd appreciate it a lot.

This is cool! I'll definitely check it out!

A misfin server implementation written in Rust is a great idea, i like the project name too.

@lux I did some testing, and it looks like the fingerprint that you are sending back on success responses has one less character than it should, I believe.

There is also another issue that I'm trying to test, so I'll have details on that later when I figure it out.

@lux Ok, the other problem I found is that your 59 error responses for bad requests doesn't have a space in it. This was also a problem in the gemini world where some people thought the spec required a space when there's no need for a META, and others thought it didn't.

According to the misfin(B) spec, I believe the space is required even when there's an empty META field because the "<SPACE>" shown in the response format is not in brackets and the spec does not explicitly call it out as optional.

However, I will modify my misfin-client code so that it will accept responses that don't have a space.

@clseibold Thanks for the suggestions! I've implemented the suggestions you mentioned in a new release:
