CNN postprocessing engine

Maturity plannedTargets FPGA + ASICDifficulty MediumPriority 1

Box decoding, score thresholding and non-maximum suppression for object detection network outputs.

Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
