Remove strum_macros and use full #[derive(Debug)]

Simpler but the debug output is incomprehensibly huge. We need to wrap all syn things in a newtype wrapper which outputs more concise debug output.

I also explored the option of a newtype wrapper in this branch but it has hundreds of compile errors and would require radical changes throughout the code.

It's possible that just using this minisyn within the Api type might make sense though.

And a third attempt here, using minisyn just for api.rs. This builds and runs, but output is still too verbose.
