Use lz4 instead of zstd for the DB

Browse Source 
zstd was recommended for the base layer only, due to its CPU requirements. That
was a misreading on mhy behalf.

lz4 gets ~5% better compression than snappy with ~30% faster performance. zstd
does ~25% better than lz4 yet at ~30% of the performance.
