Adjust DEPATISnet data source adapter to upstream changes

When loading the second chunk (250 each) of results from DEPATISnet, users reported about an error like

mechanize._form_controls.ItemNotFoundError: insufficient items with name '1000'

The reason for this problem is that DEPATISnet made some minor modifications to their systems, so the hitsPerPage variable must not be populated with a value of 1000 any more.

In other words, the upstream data source reduced the maximum page size from 1000 to 250 and we will adhere to that with the upcoming release of PatZilla.

We fixed this issue with commit [1]. It’s now also part of the most recent release [2].
