Description

to_datatime64 and to_timedelta64 don't handle mutable arrays. They raise a ValueError in trying to mask out NaN values.

Example

import dascore as dc
import numpy as np

 rand = np.random.RandomState(42)
 array = rand.random(100)
 array.setflags(write=False)

 time = dc.to_timedelta64(array)  # raises ValueError: assignment destination is read-only

Expected behavior

This should work fine.

• OS [e.g. Ubuntu 20.04]:
