Visor Development Kit 0.1.1

Changed

• The TypeScript client is published to npm by trusted publishing from this repository's release workflow, with a
  provenance statement, and no token.
• Each release also puts a copy of the libraries and of the TypeScript client on GitHub Packages, so the repository
  lists them. Maven Central, npmjs.com and PyPI stay the places to install from.
• The docs moved to visor.macedonga.com, and they name the first Visor with the VDK: Visor 3.0.0.
• The visor command installs with one line, from visor.macedonga.com/install.sh or install.ps1.
