STYLE: Enforce import of __future__ annotations (#106)

Once __future__ annotations become available the `|` notation can
be used in python 3.9. So ruff was here allowed to standardize
type annotations based on that. This will help reduce confusion about
linter complaints in the future.

 # Also, if you are using the original version, import `openlifu` takes _way_ longer (45s on my PC), presumably hanging on `import kwave`. For some reason, it wants to re-download the binaries every time, even though they are already present in the the installation directory. I've opened an issue on this: https://github.com/waltsims/k-wave-python/issues/366.
