base64 with APIs

Using base64 to decode and encode becomes really powerful if we have to handle responses from APIs.

{{ $resp := getJSON "https://api.github.com/repos/gohugoio/hugo/readme" }}
{{ $resp.content | base64Decode | markdownify }}

The response of the GitHub API contains the base64-encoded version of the README.md in the Hugo repository. Now we can decode it and parse the Markdown. The final output will look similar to the rendered version on GitHub.
