Tool chain for processing video and sound run from Cargo?

[glowmouse]

In the current repository, under assets

we have ode.oog, which is the original sound file for the proof of concept playback, ode.bin, which is the converted sound file, and convert.sh, which is the script that does the conversion.

It would be nice if ode.bin wasn't checked in, and the conversion was done by the cargo build some how. My thought is that ode.bin is similar to checking in an executable.
