Support for a search function

[aminedakhlii]

It would be appreciated if a search function (like the one supported in the native emoji picker of iOS) would be implemented and embedded into the package. Example scenario : instead of spending time searching for the 😢 emoji It would be better if users could just type sad into a the search box and the related emojis automatically appear

@aminedakhlii It should be possible to achieve it by using final filterEmojiEntities = await EmojiPickerUtils().searchEmoji("face"); (see readme) I will try to update the example soon with some sample implementation.
