The `Expr` build already includes a lot of useful filtering options, `eq, ne, gt/gte, lt/lte, and_, or_, contains, cast`, but is was missing a membership like `isin`. This PR adds that support, as minimally as possible, allowing easy filtering for membership in a list, without needing to be a series of `where` expressions. I didn't see anything in CONTRIBUTING.md about needing a feature request or issue first, so I just made the change. My apologies if I missed that somewhere. Thanks for the vector store, we're using it now in paperless-ngx.

Stable releases are created about every 2 weeks. For the latest features and bug fixes, you can install the preview release.

Once your application is stable, we recommend switching to stable releases.
