fix: Fix issue with jobs and extra whitespace on MacOS with BSD… (#145)

Browse Source 
MacOS wc has a habit of leaving nasty spaces in the output, which was
messing up our argparser.

To fix, quote the output from the jobs command, then have Rust trim out
whitespace in the jobs module before parsing.

We need to quote the output of `$(jobs -p | wc -l)` since MacOS `wc` leaves
giant spaces in front of the number (e.g. " 3"), which messes up the
word-splitting. Instead, quote the whole thing, then let Rust do the whitespace
trimming within the jobs module.
