POML v0.0.5

This is the pre-release before we actually push to public channels. Please use it as a preview of POML features.

To install the VSCode extension, download the .vsix package and click "install from VSIX" in your extension manager (thanks to stackoverflow for the image).

To install the Python SDK, use pip install poml-0.0.5-py3-none-any.whl in command line. I haven't confirmed the usability of the package yet. Development installation is still recommended.

Node.JS SDK is not packed in this pre-release.
