Add gender icons

[seb-jean]

Hi,
It would be cool to have gender icons :)
Examples:

• https://icons.getbootstrap.com/icons/gender-ambiguous/
• https://icons.getbootstrap.com/icons/gender-female/
• https://icons.getbootstrap.com/icons/gender-male/
• https://icons.getbootstrap.com/icons/gender-trans/

I'm using the icon set in elon.io, and have everything I need except for those gender icons.
