Upload GitHub release and PyPI archive

[D3vil0p3r]

Hello @JoelBender can you please upload the latest stable version of bacpypes in GitHub release and also the .tar.gz archive to PyPI?

After creating this release I realized that this issue is for the "legacy" BACpypes...

Hunting down '2.0' is not a valid metadata version problem, probably related to really old build script dependencies.
