Update to emojilib 3

[hugovk]

More emoji have been added to emojilib 3.0.2 since the last update to 2.4.0 in 2018 (and updated here in 2019 9171272).

However, 3.0.0 was a breaking change: muan/emojilib#178

Notably, the data structure and contents have changed, from:

  "pie": {
    "keywords": ["food", "dessert", "pastry"],
    "char": "🥧",
    "fitzpatrick_scale": false,
    "category": "food_and_drink"
  },

  "cake": {
    "keywords": ["food", "dessert"],
    "char": "🍰",
    "fitzpatrick_scale": false,
    "category": "food_and_drink"
  },

to:

  "🥧": [
    "pie",
    "food",
    "dessert",
    "pastry"
  ],

  "🍰": [
    "shortcake",
    "food",
    "dessert"
  ],

fitzpatrick_scale is gone but it was never used. We no longer have a distinct category.

The data is simpler: the "name" has basically been moved to the first keyword.

I've refactored the code to accommodate, and have aimed to have the same behaviour: em pie returns 🥧, and em -s food returns a long list of food.

However, there are some differences in the data, with the primary keyword changed in some cases. For example, "cake" is now "shortcake", and this matches https://emojipedia.org/shortcake/

I think this is fine, and means the emoji can be updated in the future as new emojilib updates come out. However, it's probably best to consider this a breaking change.

Please let me know if something now works differently that shouldn't (i.e. logic change rather than data change).
