Add Ninja Cat etc.

[Crissov]

As discussed in #62 and https://github.com/emojione/emojione/issues/417 we might want to add Microsoft's cat emoji sequences:

• 🐱‍👤 Ninja Cat U+1F431 + U+1F464 :bust_in_silhouette:
• 🐱‍🏍 Stunt Cat U+1F431 + U+1F3CD :motorcycle:
• 🐱‍💻 Hacker Cat U+1F431 + U+1F4BB :computer:
• 🐱‍🐉 Dino Cat U+1F431 + U+1F409 :dragon:
• 🐱‍👓 Hipster Cat U+1F431 + U+1F453 :eyeglasses:
• 🐱‍🚀 Astro Cat U+1F431 + U+1F680 :rocket:
