Support for Azure Functions using NodeJS runtime

[martindandanell]

Love what you guys are doing and can definitely see the potential in this tool.
I would like to be able to analyze my Azure Functions projects, so I have gone ahead and created a PR with a suggested approach.

Thank you soo much @martindandanell 🚀

This is such an awesome idea @martindandanell - I've been quiet caught up building our SaaS so haven't been giving much love here, but I had the azure functions as well on my mind, as well with lambda in AWS and such.

I'll take a look at your PR asap!
