v0.4.5. Lots of models. NFNets (& NF-ResNet, NF-RegNet), GPU-Efficient Nets, RepVGG, VGG.

Merge pull request #475 from rwightman/pre-release/0.4.5

Prep for PyPi release. Tweak NFNet, ResNetV2, RexNet feature extraction, use pre-act features. Also, add act args to RexNet #202

DeepMind NFNet-F* weights

Weights converted from DeepMind Haiku impl of NFNets (https://github.com/deepmind/deepmind-research/tree/master/nfnets)
