Conversion fails with unspported op FusedDepthwiseConv2dNative

[vladmandic]

Quite a few new models from TFHub fail on coversion:

vlado@Spectre:~/dev/models $ tfjs_graph_converter imagenet-efficientnet-b5 imagenet-efficientnet-b5.pb
TensorFlow.js Graph Model Converter

Graph model:    imagenet-efficientnet-b5
Output:         imagenet-efficientnet-b5.pb
Target format:  tf_frozen_model

Converting.... Error: Node module_apply_default/efficientnet-b5/model/blocks_0/depthwise_conv2d/depthwise: unsupported op FusedDepthwiseConv2dNative

Model in question is published at https://tfhub.dev/google/efficientnet/b5/classification/1

Same error with few other models published recently by Google, such as all AIY models and all EfficientNet models on TFHub.
