Seems like we do not need to introduce manyhow and darling for this crate

There's definitely no use for darling here, but I still prefer to use manyhow in macros that don't return errors, as it handles the proc_macro2::TokenStream to proc_macro::TokenStream conversion, allowing us to not mention any proc_macro types.

Done!
