Expand description

Apply syntax highlighting to pulldown-cmark events using the specified theme.

Take an iterator over pulldown-cmark’s events, and (on success) return a new iterator where code blocks have been turned into HTML text blocks with syntax highlighting.

Based on https://github.com/raphlinus/pulldown-cmark/issues/167#issuecomment-448491422.
