new feature: OpenDAL Python binding for Python 3.9

[jackye1995]

Feature Description

I try to integrate opendal into lancedb but got:

Because the requested Python version (>=3.9) does not satisfy Python>=3.10 and opendal==0.46.0 depends on Python>=3.10, we can conclude that opendal==0.46.0 cannot
      be used.

Problem and Solution

It would be nice to be able to use it without forcing python 3.10. Would be curious if the community is willing to support it, or if we recommend upgrading the minimum python version of downstream projects.
