Subject: test: stream: Add test for StreamFormat
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Test that both discrete and range based stream format descriptions
result in good discrete frame sizes. The range based stream formats
needs to be fitted with a table of resolutions inside libcamera so if
that table is updated this test might need to be updated.
