feature request: example of using cargo-watch to only convert newly saved .blend files

[ericvrp]

This would make a great DX especially in combination with Bevy's asset hot reloading!

Because blend files can link to other blend files a watch on a single blend file doesn't ensure correct scene export. Once I dealt with this using Scons to inspect the blend files to determine the relationships between them (inspecting binary using https://en.wikipedia.org/wiki/Strings_(Unix) )

That said using cargo-watch would be useful for simple examples/games
