Crate error_fatality 

Declarative annotations for fatal or jfyi error variants.

Expand #[derive(Split)] annotations on error type definitions into two additional error type definitions that can be converted back to the original, or the original can be split into one of the two generated error types. Determination of fatality can also be forwarded to an inner error that implements the Fatality trait.
