How to use a custom font?

[za-songguo]

I wonder how to use the tools in the repo to create a Rust type for other fonts, such as MiSans.
I didn't find a detailed document in the repo.

Not super easy, but you can use the Makefile as a template:

rust-embedded-graphics-cjk/font-fusion-pixel/Makefile
