Wav2letter implementation
Currently we do not have wav2letter implementation. Checkout Jasper and QuartzNet networks which were inspired by wav2letter Ok, thank you.
**Describe your question**: As Nemo is a Pytorch lightening module (as wav2letter) is there an easy to implement Wav2letter with Nemo ?

A clear and concise description of your question.
Describe what you want to achieve. And/or what NeMo APIs are unclear/confusing.


**Environment overview (please complete the following information)**

 - Environment location: [Bare-metal, Docker, Cloud(specify cloud provider - AWS, Azure, GCP, Collab)]

 - If method of install is [Docker], provide `docker pull` & `docker run` commands used

**Environment details**

If NVIDIA docker image is used you don't need to specify these.
Otherwise, please provide:
- OS version
