To prevent having to raise MSRV again, we move the debugger_visualizer
to a separate crate. This crate is only compiled when the feature
`debugger_visualizer` is enabled, because only then the
`debugger_visualizer` test is added as a compile target.

This commit implements std::error::Error for errors in the `data-url`
crate. This commit does not implement `Error` on `DecodeError` because
there is no trait bound for `Error` on the `E` type argument of
`DecodeError`.
