A simple parser for the [PC Screen Font](https://en.wikipedia.org/wiki/PC_Screen_Font) file format used to store bitmap fonts, most notably
for use in the Linux kernel's built-in console.
[Cozette](https://github.com/slavfox/Cozette) is a good sample PCF font if you're looking for one.
This crate is no_std, no_alloc, and should never panic.
# Example
```rust
let data: &[u8] = &std::fs::read("cozette.psf").unwrap();
let pcf = simple_pcf::Pcf::parse(data).unwrap();
for glyph_index in b'a' as usize ..= b'z' as usize {
for (index, pixel_on) in pcf.get_glyph_pixels(glyph_index).unwrap().enumerate() {
if index % pcf.glyph_width == 0 {
println!("");
}
if pixel_on {
print!("@");
} else {
print!(" ");
}
}
}
```
