Added Blackbird

Hi good day, Added reference to Blackbird an excellent library for asynchronous programming.

Greetings,

Hi, so is this a useful library whose topic is not covered in this list yet? Is it high-level enough, did you try it? (I'm curious, and any more feedback would be of interest to the people watching this repository). Thanks.

I suppose cl-async, by the same author, is another beast of its own and doesn't overlap Blackbird? https://orthecreedence.github.io/cl-async/

A "promise" can wrap any number of asynchronous or non-blocking operations, including but not limited to cl-async functions. It looks like Blackbird used to be part of cl-async, and was spun off into a separate library: https://orthecreedence.github.io/cl-async/future
