These looks good to me. We do need to add tests for the HIP to our GPU CI, but I don't think that's a blocker now. It's a good idea to let users start playing with this platform, imo. Thanks!

Since we have the openmm 8.2.0 rc in conda-forge should we test this PR with that rc? At least temporarily to run the CI with it. Maybe we actually need a workflow that runs CI with rc in general.

[mikemhenry]

Now that 8.2 is out, we can just double check things pass and 8.2 is pulled in

EDIT: Forgot we are explicit about the openmm versions we test

[mikemhenry]

I've added 8.2.0 to the testing matrix and removed older openmm versions.

Looks good to me. Thanks!

We need to write the tests to properly validate the platform but this is a great starting point.
