Add example to the documentation using multiple readers

[adybbroe]

Just giving an example of providing a dataset that requires multiple readers.

It was quite clear from the documentation already, but thought it was nice giving an explicit example, as at least I have been in doubt a couple of times how to do it correct.

• Closes #xxxx
• Tests added
• Fully documented
• Add your name to AUTHORS.md if not there already

I thought RTD pages should be build for the PR, so I could check it? Wasn't that the case previously? Or am I thinking of the Pyspectral repo?

Just a few typographic corrections.

Thanks @gerritholl ! That was sloppy of me, good you saw it.

[adybbroe]

Anything you are okay with @djhoese and @mraspaud and you think we can merge?
Not that it is in a hurry of course - it is just a tiny PR, so can also be forgotten easily...

I think you said this last time @adybbroe 😉 I don't remember RTD's current preferred way of requesting PRs to be built is. We do have a CI job that builds the docs which is at least a first step in catching errors. I don't remember if I made it make an "artifact" in the CI so that you can download the site and see the results. That of course could/should be replaced by RTD generation if it doesn't cost us anything.

The like might be redundant or unnecessary here. It reads a little funny.

[adybbroe]

Agree. Done.

LGTM thanks for making the changes.
