Parameterize Font

let font_data = include_bytes!("DejaVuSans.ttf");

Adopting this as my first contrib to vulkano. There's some RFC's kicking about to get better includes of files.

They just wanted manpages:
rust-lang/cargo#2729
Wound up proposing other files
rust-lang/rfcs#2376
And are.... working on it? I don't understand their process yet
rust-lang/crates-io-cargo-teams#14

In any case, since we probably don't want DejaVu shipping in binaries, I think it's safe to remove it from the lib and toss it in somewhere else, parameterizing on a file or other already-read data structure.

Did some work on Vulkano-glyph and decided not to work on this repo
