ssh-key: add SshSig serializing/deserializing using serde

[MicroPanda123]

Hello

I'm making a web server, which operates on SSH signatures, and I noticed that I could not include SshSig in my Serde Deserialized struct, so I had to parse it manually. So I decided to fork and add this functionality.

Cheers!

One nit, otherwise this looks fine

Let's see if my suggestion works 😉

[tarcieri]

Thanks!

[MicroPanda123]

Woooo!!!
Awesome, thanks!

[MicroPanda123]

@tarcieri Mind if I ask if you could perhaps push it to crates.io as 0.7.0-pre?
My project uses that, so I'd like it to be available, if you don't mind.
Thanks

[tarcieri]

0.7.0-pre.0 is already out, but I can publish another prerelease

[MicroPanda123]

Yes I'm aware just wanted it to include this PR, thank you :)

About versions, can you also write notes as releases please?
https://github.com/RustCrypto/SSH/releases

I would love being notified so I can bump afterwards

[tarcieri]

We do write release notes, but for final releases as opposed to prereleases.

Often times we'll go back and forth on various features during development, which makes it difficult to maintain prerelease changelogs.

Okay, do you mean that you will do for the next stable?
I can not see any release written on the page

[tarcieri]

We’ll publish a CHANGELOG for a stable release. We don’t use the GitHub releases feature. I use it for Rust binaries, but I don’t think it makes sense for library crates and in particular multi-library-crate repos.
