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

Add a StreamFormats class which describes all the formats supported by a
stream. The object does not collect any information itself but can
simplify user interactions with formats as it's able to translate a
stream format range into a discrete list and a discrete list to a range.
