FIX: check for dim0 if not given, only swap_dims if needed

[kmuehlbauer]

• Closes Tree can't be exported with to_cfradial2 if time is first dimension #92
• Tests added
• Changes are documented in history.md

Added cfradial2 roundtrip test and test first_dim in one go. Pulling this in, when CI finished and green.

There has been an issue with ReadTheDocs. I've reported that at RTD and they had a look immediately as it seems. Thanks RTD!
