Subject: cam: Add FrameSink base class
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The FrameSink class serves as a base to implement components that
consume frames. This allows handling frame sinks in a generic way,
independent of their nature. The BufferWrite class will be ported to
FrameSink in a second step.
