automated GithHub workflow to run test scripts

[didier-durand]

Hi,

I want to run memvid tests on Linux as a Github workflow (see yaml in this PR):

1. I had to update faiss-cpu to latest version (1.11.0) otherwise pip install -r requirements.txt: see https://github.com/didier-durand/memvid/actions/runs/15519490487/job/43690788234
2. Then, pip install goes fine. But, when I run the tests via pytest on Github with this worklfow, some of them fail: see https://github.com/didier-durand/memvid/actions/runs/15519764905/job/43691410299

Are those failures to be expected or should 100% be successful ?

If 100% supposed to be ok? Can you fix the failing tests back to ok in an additional commit to this PR before merging it?

Didier
