Use Malaya text normalization

Make sure Malaya version >= 4.7.5 to get better text normalization.

/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/tensorflow_addons/utils/ensure_tf_install.py:67: UserWarning: Tensorflow Addons supports using Python ops for all Tensorflow versions above or equal to 2.3.0 and strictly below 2.5.0 (nightly versions are not supported).
 The versions of TensorFlow you are currently using is 2.9.0 and is not supported.
Some things might work, some things might not.
If you were to encounter a bug, do not file an issue.
If you want to make sure you're using a tested and supported configuration, either change the TensorFlow version or the TensorFlow Addons's version.
You can find the compatibility matrix in TensorFlow Addon's readme:
https://github.com/tensorflow/addons
  UserWarning,
/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/tensorflow_addons/utils/resource_loader.py:103: UserWarning: You are currently using TensorFlow 2.9.0 and trying to load a custom op (custom_ops/seq2seq/_beam_search_ops.so).
TensorFlow Addons has compiled its custom ops against TensorFlow 2.4.0, and there are no compatibility guarantees between the two versions.
This means that you might get segfaults when loading the custom op, or other kind of low-level errors.
 If you do, do not file an issue on Github. This is a known limitation.

It might help you to fallback to pure Python ops with TF_ADDONS_PY_OPS . To do that, see https://github.com/tensorflow/addons#gpucpu-custom-ops

You can also change the TensorFlow version installed on your system. You would need a TensorFlow version equal to or above 2.4.0 and strictly below 2.5.0.
 Note that nightly versions of TensorFlow, as well as non-pip TensorFlow like `conda install tensorflow` or compiled from source are not supported.

The last solution is to find the TensorFlow Addons version that has custom ops compatible with the TensorFlow installed on your system. To do that, refer to the readme: https://github.com/tensorflow/addons
