Error for Keras (TF) models

1

Seems like each of the Keras models need a config.json file. For e.g. `python -m exporters.coreml --model=keras-io/transformers-qa exported/` works because this model has a config.json but `python -m exporters.coreml --model=keras-io/image-captioning...

Implement optimizations as in `ane_transformers`

2

`ane_transformers` (https://github.com/apple/ml-ane-transformers and https://machinelearning.apple.com/research/neural-engine-transformers) suggest weight-compatible changes to transformers allowing better mapping of the ops to ANE and thus resulting in significant performance improvement. @hollance do you think these optimizations...
