-j0: zero cores

It looks like -j0 using MIT/Rust Parallel literally means use 0 cores [1], while -j0 in GNU Parallel means use as many cores/jobs as possible [2]. This makes scripts that use -j0 stall indefinitely upon calling MIT/Rust parallel with the -j0 flag

  1. parallel/src/arguments/jobs.rs

    Line 15 in 17fe268

    value.parse::<usize>().map_err(|_| ParseErr::JobsNaN(value.to_owned()))

Seems silly to write -j0 when it basically means choose the default setting. Nonetheless, I'll fix this shortly.

I agree, unfortunately to be compatible as a replacement for GNU Parallel this seems to be used.

This should fix the problem.
