Posibility to use axios or enhance the current implementation to work on company proxyfied networks

[PiiXiieeS]

We have not been able to make unfurl work in internal corporate networks behind a proxy. We use regularly axios with https://github.com/TooTallNate/node-https-proxy-agent as http/https proxy agent.

Would you consider a potential transition to axios or to extend the package to make it compliant with both node-fetch and axios? Or eventually extend the current implementation to make it work behind a proxy.

Thanks for your thoughts!
