Separate the error definitions from the packages which use them.

This will allow us to keep our error definitions in a 1.0 package that shouldn't ever need a 2.0 since we are basing the errors on a fixed set.

The libraries which create and manipulate the errors are likely to change and possibly need major version bumps. If the error definitions are in the same go module, this makes the error types incompatible through type checking and requires use of the interfaces. While the interfaces may be better for version compatibility, errors.Is is the most idiomatic solution.

I assume then we need to update this once we tag a new version?
