* Sizes Parser

* By Alex Bell | MIT License
*
* Non-strict but accurate and lightweight JS Parser for the string value <img sizes="here">
*
* Reference algorithm at:
* https://html.spec.whatwg.org/multipage/embedded-content.html#parse-a-sizes-attribute
*
* Most comments are copied in directly from the spec
* (except for comments in parens).
*
* Grammar is:
* <source-size-list> = <source-size># [ , <source-size-value> ]? | <source-size-value>
* <source-size> = <media-condition> <source-size-value>
* <source-size-value> = <length>
* http://www.w3.org/html/wg/drafts/html/master/embedded-content.html#attr-img-sizes
*
* E.g. "(max-width: 30em) 100vw, (max-width: 50em) 70vw, 100vw"
* or "(min-width: 30em), calc(30vw - 15px)" or just "30vw"
*
* Returns the first valid <css-length> with a media condition that evaluates to true,
