Compile-time including of directories.
This crate works in a similar fashion as the include_bytes! macro in Rust, except it includes
a whole directory and stores them in a perfect hash function map from the phf crate.
For cross-platform consistency, backslashes in paths stored in the map are replaced with forward slashes.
All pathnames in the directory processed by the include_dir! macro must be valid UTF-8.

static TEXTURES: Map<&'static str, &'static [u8]> = incdir::include_dir!("textures");
fn main() {
// The file is stored in "files/player.png", the directory prefix is stripped in the map.
let player = TEXTURES.get("player.png").unwrap();
// Stored in "textures/world/grass.png".
let grass = TEXTURES.get("world/grass.png").unwrap()
