```python
import xarray as xr
import pickle
t = xr.cftime_range(""20010101"", ""20010520"")
pickle.loads(pickle.dumps(t))
```
Looks like pandas now passes `dtype` on to `__new__` which `CFTimeIndex.__new__` does not accept:

Might be pandas-dev/pandas#43188. So `CFTimeIndex.__new__` might need to accept `dtype`? @spencerkclark
