Download package

Download package instead of packaging it in the binary.

• Check roslyn for downloads
• Download to extension dir
• Flexible extension path

Hey @KoningJasper , question... do you know where I would need to go to get the binaries corresponding to https://github.com/KoningJasper/core-metrics/tree/master/roslyn-metrics, but for macos and linux?

Seems like a really cool extension and I want to get it working...but I don't use windows.
