Section 12.2.4.69 of the HTML spec, referenced in README.md, does not exist

Nobody has claimed this yet.

There is an issue with the reference to the HTML spec in README.md in the following part:

> This function takes a string of HTML and decodes any named and numerical character references in it using the [algorithm described in section 12.2.4.69 of the HTML spec](https://html.spec.whatwg.org/multipage/syntax.html#tokenizing-character-references).

This link I assumed would take me to section 12.2.4.69. Instead the link takes me to section 12.1 of the HTML Spec. However, if you follow a link on that page it will take you to section 12.2. Unfortunately, once you are in that section it becomes apparent that there is no section 12.2.4.69 of the HTML spec as it exists today, as section 12.2.4 ends with section 12.2.4.5. There is a section 12.2.5.69 but that does not contain any relevant algorithm.

The reference to the HTML spec should either be fixed and changed to the correct section with the link fixed to go to that section, or it should be removed entirely.

Start in README.md at the paragraph linking to section 12.2.4.69 of the HTML specification. Check the current specification structure and decide whether the reference should point to a valid relevant section or be removed. Done means the README no longer contains a broken or irrelevant specification reference.
