Should vtkio::Error implement std::error::Error?

See title. I think this would make sense and would allow for more rapid prototyping with e.g. functions returning Box<std::error::Error>.

I would happily submit a PR (once time permits...) if you agree that this could be useful.

Yes this makes sense to me. I'd be happy to accept a PR for that.
In general, I'm open to contributions that improve compatibility with the rest of the ecosystem.

This was done in 61525fe and published in v0.2.4.
It would also be nice to extend this to writer::Error but I moved that into a separate issue since it's not as important.

Closing this for now, but happy to accept improvements/adjustments.

Thanks, that's great! I haven't been actively using VTK lately (but I will soon enough), which is why I never got around to contributing the feature myself.
