Storage provider that writes ntuple pages to into a DAOS container.
Currently, an object is allocated for ntuple metadata (anchor/header/footer). Objects can correspond to pages or clusters of pages depending on the RNTuple-DAOS mapping strategy.

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 mask allows to skip writing out certain pages. The vector has the size of all the pages. For every false value in the mask, the corresponding locator is skipped (missing) in the output vector. The default is to call CommitSealedPageImpl for each page; derived classes may provide an optimized implementation though.
