Description
Ideally we'd be able to completely remove the datafusion dependency. However, I'm worried we do not have a good expression language and I think that might be required. At the very least, I believe we should be able to remove some of the heavier datafusion pieces from the crate. This crate is intended to be as lightweight as possible, ideally only depending on Arrow.

Research direction
Start by inspecting the lance-index-core dependency declaration and locating its DataFusion usages, especially any expression-language requirements. Done means removing unnecessary heavy DataFusion pieces while preserving the required expression support and keeping the crate as close to Arrow-only as practical.
