[Feature] CLI entry point

[iwr-redmond]

It would be helpful for torchruntime to be registered as its own command. This can be achieved by adding something like the below to pyproject.toml:

[project.scripts]
torchruntime = "torchruntime:main"

Good point. Like pip, I'd always advise using python -m to ensure that it installs for the correct Python version (and that it's clear which version of python is being used).

But yeah, a CLI command is useful too. Would you be interested in sending a pull request? Thanks!
