Twemoji for Chrome

Enables Chrome to display colored emojis even if your OS does not support it. Replaces the default emojis with Twemoji (Twitter emoji library).

Twemoji (v14.0 as of this publishing) adheres to the Unicode 14.0 spec and supports the Emoji 14.0 spec. More Twemoji info here:

Notable changes for v0.0.8 :
* Default CDN updated to jsDeliver
* Removed MaxCDN as an option


Quick background:
I use a Windows 7 machine where color emojis are not supported. I used several other extensions but noticed that they were rather old and did not support newer emojis. I couldn't find an updated one so I decided to create my own. Works great on my machine, so hopefully it also works correctly on yours.

Limitations:
* Only replaces emojis that are already available during the initial page load. Emojis added after via ajax, lazy-loading or other scripts will not be affected.
* Only works if browser is connected to the internet. It pulls emoji data from the internet, so replacement emojis may not appear if you're offline.
* Also, replacement emojis will not appear when viewing local HTML files.
* Uses SVG files for the replacement images so may cause issues if your browser has poor support for SVGs.
* A 2-second delay was added when loading twemojis in YouTube since YouTube partially adds/pulls/shows content on a on-demand basis. If you feel that this extension has made YouTube slow or unusable, kindly disable or uninstall this extension.
* May interfere with websites that interact with or are reliant on text emojis for their functionality. If this occurs, kindly disable or uninstall this extension.

Advantages:
* Replaces the default emoji set if you're not happy with the default emoji that comes with your OS.
* Adds emoji support to Chrome, even if not supported by the OS.
* Flags are shown correctly as actual flags, instead of the two-letter combo.
