Add a Requirements.txt rather than use conda config/channels

[taddyb]

Summary

• Given PyTorch no longer has binaries on CONDA forge, it may be wise to use requirements.txt rather than an env file
• This is more generic and can still support CONDA

Actions

• change .yaml config to a requirements.txt, or have the dependencies specified in the pyproject.toml

Considerations

Proof there is no support for CONDA

The current env yaml

name: deltamodel
channels:
  - defaults
  - pytorch
  - nvidia
dependencies:
  - python=3.11
  - pytorch::pytorch-cuda=12.1
  - pytorch::pytorch=2.5.1
  - pytorch::pytorch-mutex=1.0
  - pytorch::torchaudio=2.5.1
  - pytorch::torchvision=0.20.1

Of course we'd be grateful if you could see what you can do
