Derive Macro TryScribeString 

#[derive(TryScribeString)]
{
    // Attributes available to this derive:
    #[enumscribe]
}

Derives enumscribe::TryScribeString for an enum. This allows the enum to be converted to a Option<String> using the try_scribe() method.

This behaves almost identically to TryScribeCowStr, except the return type is Option<String> instead of Option<Cow<'static, str>>.

Since a String is returned, an allocation must always be performed, which is wasteful. TryScribeCowStr should be preferred because it avoids unnecessary allocations.
