Can't Install nemo_text_processing
@mschonwe we changed a few things regarding normalization since 1.0.0rc.
 please refer to RC tutorial https://github.com/NVIDIA/NeMo/blob/r1.0.0rc1/tutorials/tools/Text_Normalization_Tutorial.ipynb which is tested to work in nvcr.io/nvidia/nemo:1.0.0rc1. Thank you.  Got it working following the updated tutorial. @mschonwe  we will be soon changing text normalization to WFST just like inverse text normalization, just FYI
I'm following the instruction in
`https://github.com/NVIDIA/NeMo/blob/main/tutorials/text_processing/Text_Normalization_Tutorial.ipynb`

Running code on a docker container `nvcr.io/nvidia/nemo:1.0.0rc1`

There are no errors when running the suggested install code:
```
BRANCH = 'main'
!python -m pip install git+https://github.com/NVIDIA/NeMo.git@$BRANCH#egg=nemo_toolkit[nlp]
```
Many lines of `Requirement already satisfied:...`

However, the `import nemo_text_processing` fails:
```
ModuleNotFoundError: No module named 'nemo_text_processing'
```
