could be good to check the benchmarks run before approving/reviewing this PR (maybe only running the compression temporarily to check it works fine)

Ok, I think this needs attention from someone more familiar to integer benchmarking and slab. It seems that we need to generate parameter files in tfhe/benchmarks_parametersfor these new benchmarks, and I think these may not be the last modifications we need to do.

I will rollback to the original strategy of having all compression benchmarks on a separate file, just as the CPU does, so we fix GPU's integer benchmarking. When @agnesLeroy or @soonum are back we return to this topic and (maybe) refactor both benchmark sets.
