- [x] Closes #6226
- [x] Added tests for opening netcdf files with cftime axis in parallel

This PR tries to address some updates in the pandas library on how datetime objects are pickled. Since I was told that the datatype of the CFtimeIndex object will always be `object` I just instructed the `__new__` method to receive any additional arguments but not to evaluate them. Which feels a little awkward but does the job. If there are better ways to deal with this please let me know.  @spencerkclark @aidanheerdegen @mathause ","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/6249/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,,13221727,pull
