Include more html header tags to be used a sections when chunking

Currently with version 2.3.3, when parsing and chunking html, it chunks into sections based on heading tags and creates metadata with "headers" key with section title as the value. This is only working for h1 through h3 tags, while h4 through h6 tags are ignore and treated as regular text.

Can this plugin be updated to include all heading tags h1 through h6 ?
