Feature Request: joblog option

[galiagante]

This would reproduce the --joblog feature seen in current versions of GNU Parallel.

Handy for troubleshooting or for tasks that otherwise require information on the exit values of tasksrun via Parallel

This is a status update that I'm getting fairly close to completing the job log feature. I have a trivial logic error to track down and some other unrelated refactoring to do, but I might have it completed by the end of tomorrow. The implementation avoids heap allocations. Integers are directly converted into a shared stack-allocated &[u8] and written directly to the buffered file, so there should be zero performance overhead to implementing the new feature.

Just an update that you might be interested in the new time format (--joblog-8601)
