Add Emery (with another name)

**Font Project Git Repo URL:**

https://github.com/googlefonts/emery-3

**Super short description of the Font Family:**

Christian Mosmüller emailed fonts@ with,

> I am writing to submit my font, Emery³, for consideration to be included in the Google Fonts library. Emery³ is a striking, variable Display Font specifically designed for animation on the web, featuring three variable axes.
>
> Feel free to also use my website to check out the font: https://cmosmueller.ndu.schulwebspace.at/varWeb/
>
> As the sole original author of Emery³, I would like to declare that I hold all the necessary rights to license the font under the Open Font License (OFL).
>
> Enclosed in this email is the source file for Emery³ as well as a variable TTF file, which is available for you to take care of everything else. I believe that Emery³ would be a great addition to the already impressive collection of fonts available on the Google Fonts website.
>
> Thank you for considering my submission. I look forward to hearing back from you soon.

I created a Github repo for it, above.
