Description
polygraphy: print or validate_output for struct FormattedArray is unsupported, while my trt engine's output is reformated to fp16:hwc8.
error log from polygraphy run of my trt:
Function: dtype is unsupported for objects of type: FormattedArray
Function: mean is unsupported for objects of type: FormattedArray
Function: size is unsupported for objects of type: FormattedArray

Research direction
Start by reproducing polygraphy run with a TensorRT engine whose output is formatted as fp16:hwc8, then trace how FormattedArray is handled by the print and validate_output paths. Done means these paths no longer fail on the reported dtype, mean, and size operations.
