Overhauls the derive macro to better support removing fields in a enum variant and removing the fields of types which are no longer used in the latest revision.
This PR introduces field structs for enum variants.
When a field is removed from an enum variant, the convert function now looks like
fn(&mut FieldStruct,revision: u16, value: T) -> Result<()>whereFieldStructis a generated struct which has the same fields as the variant has at the current revision.Furthermore when a variant is removed the convert function now takes this field struct as an argument.
This PR also introduces an option to override the default generated discriminant values for enum variants. This is useful for compatibility with previous versions of revision which had different behavior.
