Comment (by wenzeslaus):
Replying to [comment:26 mmetz]:
> The patches compressors.patch and compressors.patch are also updated to
properly support NULL compression. Data for the null2 file are now
compressed with the same method like actual raster values.
Tested with `GRASS_COMPRESSOR=LZ4`, `GRASS_COMPRESSOR=BZIP2` using the
[comment:27 command above] but as I mentioned here or in #2349, the test
do not cover NULL files well.
