libpressio?

[mathomp4]

As we explore tools to better compress GEOS NetCDF4 output, one interesting set of tools looks to be the pressio suite of @robertu94:

https://github.com/robertu94/libpressio
https://github.com/robertu94/pressio-tools

where the latter has a CLI:

pressio -i ~/git/datasets/hurricane/100x500x500/CLOUDf48.bin.f32 \
    -b compressor=sz3 -o abs=1e-4 -O all \
    -m time -m size -m error_stat -M all \
    -w /path/to/output.dec

I'm really interested in that if we use Spack, we can define a lot of variants to let us test:

Thanks to @robertu94 for adding so many. Now the spack packages do seem a bit out of date (there is a pressio 1.0.4 and 0.5.3 currently but those aren't in spack), but I can add them when I test (and then submit up to spack-packages).
