[proposal] (De)serializing (to)from structured types

[clamydo]

The JSON3 package uses StructTypes to map data from a JSON-file into a Julia data structure. See https://quinnj.github.io/JSON3.jl/stable/#Read-JSON-into-a-type

Potentially, this approach offers a more type safe alternative to the current Dict based approach. It basically allows to specify a schema of the YAML file as a Julia type, which can be validated while parsing.

Perhaps, this package could follow a similar route?

This concept is also used very successfully by Rust's serde crate.

This issue arose in #70

I think it's a great idea. Over on #70 , @christopher-dG also commented:

YAML has tags to facilitate that, we could do something similar to what pyyaml does

Alternatively just using StructTypes would also be really good

Would be very nice to have!
