Add a CLI component to enable rewrites

* Add flags for rewrite (--rewrite, --rewrite-start,
  --rewrite-end, --rewrite-target)
* Refactor CLI interfaces to accept tflite models with optimize for
  rewrite, keras models with optimize for clustering and pruning
* Refactor and move common.py and select.py out of the folder
  nn/tensorflow/optimizations
* Add file nn/rewrite/core/rewrite.py as placeholder
* Update/add unit tests
* Refactor OptimizeModel in ethos_u/data_collection.py
  for accepting tflite model case
* Extend the logic so that if "--rewrite" is specified, we don't add
  pruning to also accept TFLite models.
* Update README.md
