WIP: pareach module, wraps rust-parallel to bolt on parallelism

[JeffMelton]

I just threw together a quick PoC at murex-module-pareach. Very basic at this point, but it captures the idea. Hoping to expose several of the rust-parallel flags to the module.

I'm not sure this is going anywhere, either. rust-parallel spawns a new murex process for each item, and it seems to be hitting the same bottleneck we see with in-murex parallelism.

I've been quietly reviewing the pipe code I'd written way back.

Basically to support typed pipes but also natively support traditional unix command line tools, I built a wrapper around POSIX pipes. That was some pretty early code in Murex and much of the code is basically just written to make pipes thread-safe.

The Go ecosystem has grown massively since and I can see there's now a lot better tools available for managing concurrency than what I've used. So there's a chance I can make some pretty major performance improvements there.

I'm hoping to get a POC branch pushed over the weekend and can then do some benchmarking for comparison.
