    WindowMappingFn maps from a main input window to a side input window,
    and provides a maximum amount of lookback that is possible to generate
    using the MappingFn. This separates the logic of assigning windows from
    the logic of mapping main and side inputs. Additionally, it permits
    pipeline runners to garbage collect side inputs when they are no longer
    accessible.
    
    This is currently unused.
    
    See BEAM-846 and BEAM-260 for additional context.
