run fuzzers with -jobs (or -workers?) for parallelism

github actions provides two cores, but clusterfuzzlite only uses 1. passing -j $(ncpu) gets free extra capacity :-)

Yeah we definitely should do this. I didn't out of caution for stability purposes, but it is worth a try.

If you throw it behind an experimental option or something that's fine by me :-)

Sorry I'll land this on Monday

Nice addition, thanks! Shouldn't this be added to the docs, too?

Yup. I'll try to get around to this tonight

Implementation and docs are done, so this issue can be closed, right?
