Allow aligning with serde annotations

[TheNeikos]

Context

Some types that are annotated with a type description are also annotated with serde tags. Since TypeDescriptions are not meant to be used for serialization this is fine, however for some configs this could mean there is a mismatch between the given config and what serde expects.

An example:

#[derive(Deserialize, TypeDescription)]
struct SimpleConfig {
  #[serde(rename = "the_name")]
  name: String
}

While TypeDescription will continue to report name, serde expects a the_name field.

This feature request is to add a mechanism to align them both.

Alternatives

An alternative is to not have an alignment feature, and instead have the user manually add the required annotations.

If the feature request is approved, would you be willing to submit a PR?

Yes :)

With #117 merged, we now support several serde attributes.

There are still a few missing, notably anything regarding names.
