Should we change the license to MIT?

[sout233]

vst3sdk released version 3.8.0, and replaced the original GPLv3 license with MIT.

My opinion is that new projects should prefer vst3-rs and vst3-sys which are more actively maintained and superior to this crate, which uses some awfully complicated proc macro programming instead of generated bindings.
