Hey @sky-2002 , thanks a lot for making this PR! I think it's almost good to go, just a couple of small comments.

One other comment: could you also add Voyager to the tested backends? It should be as simple as adding Voyager here: https://github.com/MinishLab/vicinity/blob/main/tests/conftest.py#L32, and running make test to see if everything works as expected.

A couple of other comments:

• could you also add voyager to the requirements file? You can add a voyager dependency like the one here https://github.com/MinishLab/vicinity/blob/main/pyproject.toml#L65, and then also add it to the all dependency group
• could you update the documentation to also include voyager? There's 3 parts where it can be included: supported backends, backend parameters, and installation.

Thanks in advance!

@sky-2002 voyager isn't installed in CI yet, which is why these tests all fail. Could you add it to the list of extra in the Makefile?

Approved, thanks for this addition!
