Context R-CNN Updates: Added capabilities to use multi-headed or multi-layered attention, to place the attention heads pre- or post-second stage feature extraction, and to work with embedded features in the context feature back from pre- or post-second stage feature extraction. Added an option for RPN feature map crops to be piped through to model outputs.

DEFAULT_VALUE_OK=setting prefetch batches default to 2 as using -1 can cause memory issues for some models such as context r-cnn that use sequence examples.

Add a temporal offset prediction head to improve tracking accuracy, similar to "Tracking Objects as Points"(https://arxiv.org/abs/2004.01177).
Notice that the original paper requires a change to the input pipeline, which is not included in this commit.
