to be cumbersome to read and make sense of in the PipelineHandlerIPU3

which sink to configure with a specific function for each sink.
This makes the code easier to follow as it's always clear which of the
ImgU sinks are being configured without knowing the content of a
generically named variable. It also paves the way for future

This is potentially wasteful, as each stream could allocate just as many
buffers as requested by the application instead of the maximum from the

pipeline and should be fixed on top after the decoupling of the two
