[Rust] [Parquet] Expose SliceableCursor and FileSource #26379
Description
7155cd5 Reworked how the parquet reader traits were implemented to be interms of a ChunkReader trait (for the better, in my opinion).
That commit includes two helper classes, SliceableCursor and FileSource, which implement ChunkReader for a Cursor like thing and Files, respectively
My project uses the parquet SerializedFileWriter with things that look like File and Cursor and thus I would like to re-use the logic in SliceableCursor and FileSource without having to copy/paste them.
