add meta.json?

[Habbie]

hi! I'm using this repo as a git submodule for a non-web project, to get the .ttf. While I know the .ttf contains mdi:foo name information, this is not always easy to get out of it.

In https://github.com/Pictogrammers/pictogrammers.github.io/tree/main/%40mdi/font/7.3.67 I noticed a very convenient meta.json. Is there any chance you could add it to this repo too?

Alternatively, I can parse scss/_variables.scss, assuming that one is sticking around. Please let me know what makes sense to you.

Thanks!
