Use emoji-regex for a better compatibility?

[SaekiRaku]

\p{Emoji} is not compatible with Chrome 52 as I tested.

unicode-emoji-toolkit/index.js

Line 10 in 266b6d8

const emojiRegex = /((\p{Emoji})|(\p{Emoji_Presentation})|(\p{Emoji_Modifier})|(\p{Emoji_Modifier_Base})|(\p{Emoji_Component})|(\p{Extended_Pictographic}))*/gu

Maybe use emoji-regex is better?
