add in-extension filtering at row-group level #2

Closed cldellow closed 6 years ago

Like #1, but do it at the row group level. This further increases efficiency by avoiding the need to open row groups that we know cannot satisfy the query.

Support for strings, ints, doubles, bools, variable length blobs.
