Updates on Qrack simulator

[WrathfulSpatula]

I'm from over on the Qrack simulator project. Thank you for these awesome resources! I wanted to let you know that we've iterated Qrack, and a number of your metrics on the project might be out of date, by now.

• We switched to LGPL (from GPL) several months ago to ease integrations into stacks, like with ProjectQ and SimulaQron.
• In addition to Linux and Mac (Mojave), we've finished adding support for Windows 10 builds with CMake and Visual Studio. (We also support the Raspberry Pi 3, now.)
• We've added code for several example executables, and we've updated our documentation, including adding a CHANGELOG.md and a CONTRIBUTING.md.
• We've had a Discord server at https://discordapp.com/invite/Gj3CHDy this whole time, but we failed to let people know clearly via the repo. We've added it to the README.
• We've had some more external involvement in Github issues, and the corresponding metrics might be out of date.

Thank you again! We're following qosf.org, and we hope Qrack can be a useful resource to everyone!
