Feature Request: Gendered emojis

[leb-kuchen]

Genders were mentioned in #1, but I think they've been forgotten.
This could be generated by the code points or the names of the emojis.

This is definitely possible, but it doesn't seem to be as concretely defined in the spec as skin tones are. Skin tones always follow particular code points but for gender the actual base code point for the emoji is different for man, woman, person variants. Not sure if there is a pattern. It might require a somewhat manual mapping. Some examples:

1F64E                # 🙎 E0.6 person pouting
1F64E 200D 2642 FE0F # 🙎‍♂️ E4.0 man pouting
1F64E 200D 2640 FE0F # 🙎‍♀️ E4.0 woman pouting


1F9D1 200D 1F373 # 🧑‍🍳 E12.1 cook
1F468 200D 1F373 # 👨‍🍳 E4.0 man cook
1F469 200D 1F373 # 👩‍🍳 E4.0 woman cook

Proposed API

enum Gender {
    Neutral,
    Male,
    Female,
}

impl Emoji {
    pub fn gender(&self) -> Option<Gender>;
    pub fn genders(&self) -> Option<impl Iterator<Item = &Self> + Clone>;
    pub fn with_gender(&self, gender: Gender -> Option<&Self>;
}

These example you have listed are the main patterns:

1. {BOY,GIRL,CHILD,MAN,OLD_MAN_OLD_WOMAN,PERSON}
2. ZWJ GENDER

There are a few exceptions, and the subgroup family requires special handling.
For the 1st case, the first character needs to be replaced.
For the 2nd case, the gender symbol needs to be replaced or added.

And it would also be useful to add an age field.
