os.sched_getaffinity not available on MacOS

[danudwary]

Something I noticed while attempting to run bligslice on my Mac: os.sched_getaffinity import failure due to lack of sched_getaffinity in Mac python's os package. This would be a problem on Windows, as well, I expect. Not a big deal for me, personally, as I normally run elsewhere, but may want to address if you want more compatibility.

$ bigslice --help
