Add GTL001

https://github.com/eliheuer/GTL001

GTL001 is the first typeface released by GTL Type Label and was drawn and engineered by Eli Heuer. The design takes inspiration from happy hardcore music graphics and 90's rave fliers. A 100/100 NFT for this typeface was minted on [Zora](https://zora.co/collections/0xb013e4f218760bb72f63f8d78a82b546c91897ef), and an essay titled “[Libre Type as a Veblen Good](https://www.nan.xyz/txt/libre-type-as-a-veblen-good/)” was written about the project.
