Derive Macro strum_macros::EnumTryAs

#[derive(EnumTryAs)]
{
    // Attributes available to this derive:
    #[strum]
}

Generated try_as_*() methods for all tuple-style variants. E.g. Message.try_as_write().

These methods will only be generated for tuple-style variants, not for named or unit variants.
