autogen-stedi 0.3.2

// Guards the datetime query-param rewrite in scripts/fix-datetime-query-params.py: the
// upstream rust generator serializes chrono DateTime query params via Display, which is
// not RFC 3339 and is rejected by the Stedi API. If a regeneration ever reintroduces the
// raw `to_string()` serialization, this test fails.
