      decompressIterative() shouldn't rematerialize BSONElements. We can use appendPreAllocated to append the materialized elements we receive from the iterator decompressor. This should speed up the benchmarks added in SERVER-85176. This function is just used for testing, so speeding this up will just give us a better look into how much the new decompressor implementation affects the runtime.
