Figure out how to package fonts

[MelissaAutumn]

We don't want to base64 and embed the fonts into style.css because we want to be able to tree-shake any extra font resources. However including the resources in public doesn't seem to work as expected.

We could just not include the fonts in the build and expect the consumer of this library to bring them in a specific directory.
