for iterating through ``list_files`` requests.

This class thinly wraps an initial
:class:`google.ai.generativelanguage_v1alpha.types.ListFilesResponse` object, and
provides an ``__iter__`` method to iterate through its
``files`` field.

If there are more pages, the ``__iter__`` method will make additional
``ListFiles`` requests and continue to iterate
through the ``files`` field on the
corresponding responses.

All the usual :class:`google.ai.generativelanguage_v1alpha.types.ListFilesResponse`
attributes are available on the pager. If multiple requests are made, only
the most recent response is retained, and thus used for attribute lookup.
