Reverse lookup fixes and enhancements. (#15611) 
* Reverse lookup fixes and enhancements.

1) Add a "mayIncludeUnknown" parameter to DimFilter#optimize. This is important
   because otherwise the reverse-lookup optimization is done improperly when
   the "in" filter appears under a "not", and the lookup extractionFn may return
   null for some possible values of the filtered column. The "includeUnknown" test
   cases in InDimFilterTest illustrate the difference in behavior.

2) Enhance InDimFilter#optimizeLookup to handle "mayIncludeUnknown", and to be able
   to do a reverse lookup in a wider variety of cases.

3) Make "unapply" protected in LookupExtractor, and move callers to "unapplyAll".
   The main reason is that MapLookupExtractor, a common implementation, lacks a
   reverse mapping and therefore does a scan of the map for each call to "unapply".
   For performance sake these calls need to be batched.

* Remove optimize call from BloomDimFilter.

* Follow the law.

* Fix tests.

* Fix imports.

* Switch function.

* Fix tests.

* More tests.
