Module selection 

Physical row selection for late materialisation.

PhysicalSelection is a set of non-overlapping, ascending physical row ID ranges. It is the output of crate::PermutationIndex::to_physical_selection and can be trivially converted to parquet::arrow::arrow_reader::RowSelection by downstream consumers (the conversion lives outside this crate to avoid a parquet dependency).
