Comment (by sprice):
Probably related to #2750, where I've implemented LZ4, LZ4HC, and ZSTD
support in GRASS for up to 3x speedup in I/O bound modules.
GRASS_COMPRESS_NULLS is slightly slower than not when using the original
ZLIB, but faster when using LZ4. LZ4 does a better job compressing null
files than ZLIB, in addition to the speedup.
