Re: [I] FixedShapeTensorArray.to_numpy_ndarray() fails with numpy arrays of type string in Pyarrow-16, but works with v15 [arrow]

   I wasn't aware `FixedShapeTensorArray` could be constructed with strings, are you sure your data round trips unchanged?
   
   As a workaround you could change `_extract_element_feather` to this:
   ```python
   def _extract_element_feather(column: Any):
       import pyarrow as pa
   
       if type(column) == pa.lib.FixedShapeTensorArray:
           return column.storage.to_numpy(zero_copy_only=False)
       else:
           return column.as_py()
   ```
   
   When `FixedShapeTensorArray` was built we didn't expect it'd be used for strings. However if there's need for it we can have a discussion and see if we could accommodate the usecase.
