Fixes all of the MIT/Apache-2.0 to the more valid (but semantically same) MIT OR Apache-2,0
Includes the licenses in the gltf crate
Copies the LICENSE-MIT and LICENSE-APACHE files into the two subcrates so that the licenses are part of the packaged crates, though in the case of the gltf_derive crate, the existing LICENSE is just renamed to LICENSE-MIT to preserve the different attribution for that particular crate
