LUCENE-10170: Restore compression speed for LZ4. (#377)
A slowdown had been introduced in LUCENE-7521.
> Regression in stored fields compression in 9.0

> One of the Elasticsearch benchmarks detected a regression that is attributed
> to stored fields compression after moving to a 9.0 snapshot. I managed to
> isolate it to the change done on LUCENE-7521. It looks like LZ4 relied
> significantly on Direct16 for good performance, so replacing it with Packed64
> degraded compression speed.
