Overview

Package srcset `srcset` provides a parser for the HTML5 `srcset` attribute, based on the [WHATWG reference algorithm](https://html.spec.whatwg.org/multipage/embedded-content.html#parse-a-srcset-attribute). TODO: This works, but I dislike the state manipulation. Use more go-like structures for reading and tokenization, like bufio.Scanner
