Describe the bug

In sunpy we're getting a bunch of warnings that look like this, and are coming from drms:

FutureWarning: In a future version, `df.iloc[:, i] = newvals` will attempt to set the values inplace instead of always setting a new array. To retain the old behavior, use either `df[df.columns[i]] = newvals` or, if columns are non-unique, `df.isetitem(i, newvals)`

@nabobalis as per #73 (comment) could you re-open this?
