Add deserr to the list

[irevoire]

Hey 👋

I’m working at @meilisearch, and we developed a cute crate called deserr 🍰
The purpose of this library is to provide an easy way to deserialize payloads in a user-facing API.

You could say that serde is already enough, but we found out it was missing a lot of features, especially when it comes to error handling. That’s the gap we’re trying to close here.
Also, since it’s used at meilisearch, it should stay maintained.
And since we provide an actix-web extractor (and soon enough, an Axum extractor), it’s easy to integrate into your web API.
