custom emoji shortcodes in 11ty with a plugin

hey i did a thing, here markdown-it-emoji-customizer

it's a plugin for 11ty, as a helper module for markdown-it-emoji, so it's possible to easily have custom emoji/icon shortcodes!

it:

• takes in your md library from 11ty
• scans a dir for custom emoji images
• makes the definitions (the shortcodes and info about what image the shortcode refers to)
• optionally also converts shortcodes for standard unicode emoji to their unicode equivalent
• makes an <img> with custom attributes for the custom emoji, wrapped in a <span> with a custom class (specific to these custom emoji image spans)
• wraps the unicode emoji that were converted from shortcode (if any) in a <span> with a custom class name (specific to these unicode emoji spans)
• also includes some (optional) basic css snippet to try to make the custom emoji and unicode emoji a bit more uniform in appearance (at least on my site, on my device lol)
• returns the modified md library

so when the site is built, if you have some markdown like:
:cat: :arrow_left: *unicode!*
:neocat: *custom!*
you'll get something like:

🐱 ⬅️ unicode!
custom!
