   # Which issue does this PR close?
   
   - Closes #8518.
   
   # Rationale for this change
   
   This builds on #8763 to add options to either skip decoding of the page 
encoding statistics array, or transform it to a bitmask. This gets rid of the 
last of the heavy allocations in the metadata decoder.

   Adds new options to `ParquetMetaDataOptions`. Also adds more metadata 
benchmarks.
   
   # Are these changes tested?
   
   Not yet, but tests on the way.
   
   # Are there any user-facing changes?
   No, just adds new field to `ColumnChunkMetaData`.
