FIX: got rid of type: ignore[unreachable] comments #221

[Saswatsusmoy]

Description

Fixes #221
To fix this, we can use a TypeVar to bound the input cls to VectorProtocol. This avoids the inconsistent inheritance issue.
We also don't need the unreachable ignores anymore since the code now typechecks correctly.

Thanks for taking this up, @Saswatsusmoy! Could you please add warn_unreachable = true under the [tool.mypy] section in pyproject.toml to check if this works?
