  1. options: Add StreamRole::Viewfinder when enumerating for --list-cameras 

    The change for rpi::ScalerCrops changes the behaviour of how crops are
advertised - we now need a non-RAW output stream to be configured to
return the available crop control.

  2. postprocess: hailo: Handle multiple scaler crops on the ISP outputs 

    Add a HailoPostProcessingStage::ConvertInferenceCoordinates() helper
that converts from the inference (low res) image co-ordinate space
to the main image space, accounting for different scaler crops.

Fixup the Yolo inference and pose estimation stages to use this new
helper.

  3. core: Add aspect ratio control for lores stream 

    Add a new command line argument "--lores-par" that when set, preserves
the 1:1 aspect ratio of the low res stream. This is only possible on the
PiSP platform. The default behaviour is to have this switch disabled,
allowing for identical behaviour betwen VC4 and PiSP platforms. This
requires the use of the rpi::ScalerCrops vendor control.

This switch can also be triggered via the "rpicam-apps.lores.par" key
in the postprocessing JSON file.
