Attribute for externally tagged enums or match serde by default

[Heliozoa]

Hi,
currently the the TS::decl() generated for a type like

#[derive(serde::Serialize, TS)]
enum Enum {
    A(&'static str),
    B { s: &'static str },
    C
}

looks like this

type Enum = string | {
    s: string,
} | "C";

whereas serde_json generates output matching the type

type Enum = { "A": string } | { "B": { s: string } } | "C"

serde-compat allows for matching other styles of representing enums, like #[serde(tag = "tag", content = "content")], but there's no way to match the default since there's no serde attribute for it. I think matching serde's default output is preferable since it allows for differentiating between A("C") and C, but an attribute would work too.

I'm currently working on this.
In case you want to help, a few tests testing this behaviour, including its interaction with #[ts(inline)], would be tremendously usefull!

What's working so far:

#[derive(TS)]
enum SimpleEnum {
    A(String),
    B(i32),
    C,
    D(String, i32),
    E(Foo),
    F { a: i32, b: String },
}

generates (output formatted)

type SimpleEnum =
  | { A: string }
  | { B: number }
  | "C"
  | { D: [string, number] }
  | { E: Foo }
  | { F: { a: number, b: string } };

Which does seem to match serdes default "externally tagged" representation:

{"A":"foo"}
{"B":5}
"C"
{"D":["bar",123]}
{"E":{"bar":{"field":44}}}
{"F":{"a":42,"b":"baz"}}

though #[ts(inline)] is not behaving like it should

fixed in v6.0.0
