Description

When writing a file to feather, you get those warnings:

In [45]: pd.DataFrame({'a': [1, 2, 3]}).to_feather('test.feather')

/home/joris/scipy/repos/arrow/python/pyarrow/feather.py:97: FutureWarning: Calling .data on ChunkedArray is provided for compatibility after Column was removed, simply drop this attribute
  self.writer.write_array(name, col.data.chunk(0))

Since they are coming from pyarrow itself, we can (should) fix them.
