Vector commit of preprocessed pages.
The ranges array specifies a range of sealed pages to be committed for each column. The returned vector contains, in order, the RNTupleLocator for each page on each range in ranges, i.e. the first N entries refer to the N pages in ranges[0], followed by M entries that refer to the M pages in ranges[1], etc. The default is to call CommitSealedPageImpl for each page; derived classes may provide an optimized implementation though.
