> Currently ScanOptions has two distinct responsibilities: it contains the data selector (and eventually projection schema) for the current scan and it serves as the base class for format specific scan options.
> In addition, we have ScanContext which holds the memory pool for the current scan.
> I think these classes should be rearranged as follows: ScanOptions will be removed and FileScanOptions will be the abstract base class for format specific scan options. ScanContext will be a concrete struct and contain the data selector, projection schema, a vector of FileScanOptions, and any other shared scan state.
