   I was also thinking: instead of adding heuristics as we try to do here we 
could avoid "fragmented" selections.
   We could "unfragment" the selection instead by only call `skip` whenever 
this chunk is all false, but just decode and post-filter based on a boolean 
selection in other cases. 
   That would avoid the nasty interleaving of skip / read but still  benefit 
from more filters that are effective on part of the row filter.
