Scryer-prolog: sleep/1 may be an interesting small project for Rust programmers

[triska]

As another small self-contained project that may attract more contributors (#319):

sleep(T) shall sleep for T seconds (a floating point number).

Rust provides thread::sleep() for this:

https://doc.rust-lang.org/std/thread/fn.sleep.html

library(time) would be a good place to provide sleep/1. See https://github.com/mthom/scryer-prolog/pull/367/commits/4693c23a4970cdc3437d75b1e61df768282b48fa for an example of how predicates can be added to Scryer.
