Re: [PR] perf(parquet): single-allocation intersect_masks/union_masks for unequal lengths [arrow-rs]

   Hi @alamb @hhhizzz , this pr makes the uneven-length intersection/union copy once instead of twice — 18–34% faster, or 61–83% when the masks aren't byte aligned. Also adds a benchmark for the path. ready for reviews.
