Hyperion-ml

- Fix bug in model loader for older x-vector models

- Fix bug in model loader for older x-vector models
- Fix bug in visual recipes
- Adds some docs

- Breaking Changes:
- s parameter in x-vector AAM/AM softmax loss is renamed as cos_scale to avoid conflict with other arguments that start with s. Models trained with older versions still should work.
- Launcher for multigpu has been changed to the newer torchrun, it implies the multigpu won't work on PyTorch <1.9.
- Hyperion updated to work with PyTorch >=1.9, PyTorch 1.10 recommended.
- Documentation automatically uploaded to https://hyperion-ml.readthedocs.io

- This release, should upload automatically to pypi

- All Code formatted with Black
- Added GitHub Action to check for black formatting

- Changes in requirements, current version only works with
- Pytorch >=1.6 <= 1.8.0
- Fairscale = 0.3.8
