Implement convertors to and from Polars DataFrames in Rust SDK using convertors based on C FFI #1099 (#1260)

Browse Source 
https://github.com/lancedb/lancedb/issues/1099

Took the same general approach from:
https://github.com/lancedb/lancedb/pull/1235. Instead of using
high-level convertors implemented in polars-arrow (with the arrow-rs
feature flag, which adds a dependency on arrow-rs), I used convertors
based on the C FFI to avoid dependency conflicts.
