* twemoji.parse(HTMLElement, Function);
* twemoji.parse(HTMLElement, Object);
*
* @param string|HTMLElement the source to parse and enrich with emoji.
*
* string replace emoji matches with <img> tags.
* Mainly used to inject emoji via `innerHTML`
* It does **not** parse the string or validate it,
* it simply replaces found emoji with a tag.
* NOTE: be sure this won't affect security.
*
* HTMLElement walk through the DOM tree and find emoji
* that are inside **text node only** (nodeType === 3)
* Mainly used to put emoji in already generated DOM
* without compromising surrounding nodes and
* **avoiding** the usage of `innerHTML`.
* NOTE: Using DOM elements instead of strings should
* improve security without compromising too much
* performance compared with a less safe `innerHTML`.
*
* @param Function|Object [optional]
* either the callback that will be invoked or an object
* with all properties to use per each found emoji.
*
* Function if specified, this will be invoked per each emoji
* that has been found through the RegExp except
* those follwed by the invariant uFE0E ("as text").
* Once invoked, parameters will be:
*
* codePoint:string the lower case HEX code point
* i.e. "1f4a9"
*
* options:Object all info for this parsing operation
*
* variant:char the optional uFE0F ("as image")
* variant, in case this info
* is anyhow meaningful.
* By default this is ignored.
*
* If such callback will return a falsy value instead
* of a valid `src` to use for the image, nothing will
* actually change for that specific emoji.
*
*
* Object if specified, an object containing the following properties
*
* callback Function the callback to invoke per each found emoji.
* base string the base url, by default twemoji.base
* ext string the image extension, by default twemoji.ext
* size string the assets size, by default twemoji.size
*
* @example
*
* twemoji.parse("I u2764uFE0F emoji!");
* // I <img class="emoji" draggable="false" alt="❤️" src="/assets/2764.gif"> emoji!
*
*
* twemoji.parse("I u2764uFE0F emoji!", function(icon, options, variant) {
