Add Miama

**Font Project Git Repo URL:**

None I could find; I added this to what is now this repo in 2011 and then it wasn't added since the number of OpenType alternates made the filesize unreasonable, but since we now have CJK fonts, I think we can finally add it.

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

This is at https://github.com/google/fonts/blob/main/ofl/miama/DESCRIPTION.en_us.html and notably says

> Miama is a very small typeface compared to other fonts. This is due to the very large ascenders and descenders. So if you want to look Miama as a font of 10pt, choose 15-20pt. Also keep in mind, that Miama then still looks quite light, so you want probably resize it even more for titles.

So we might want to re-scale it, using our latest vertical metrics techniques.

**Requirements:**

- [x] The entire font project is licensed under the [OFL](https://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&id=OFL)
- [ ] There is no "Reserved Font Name" mention in the OFL license

Sadly https://github.com/google/fonts/blob/main/ofl/miama/OFL.txt says

> Copyright (c) 2008-2011, Linus Romer, with Reserved Font Name Miama.

so we'll need to reach out to Linus and find out if he has a source repo, and will remove the RFN.
