rectangular gridAnchorPlugin support for tensorrt7

Description

Is there a particular reason why the rectangular feature map support for Achor Plugin support for tensorrt7 has not been upgraded from tensorrt6 ?

Also How do I make it work for rectangular input ? (720 , 1280) I am getting an error : https://github.com/NVIDIA/TensorRT/blob/master/samples/opensource/sampleUffSSD/sampleUffSSD.cpp#L179

I think that the reason is that the plugin GridAnchorRect_TRT is bugged, see #247.

@rmccorm4 Any updates on this issue will be helpful ? As giving rectangular inputs is a basic need.
