unnamed enum issue on macos

[kcking]

When using vst3-bindgen in a blank project, i get the following compilation error:

error: expected identifier, found `(`
  --> /Users/.../target/debug/build/vst3-bindgen-2dd1585f0690fcd4/out/bindings.rs:25:14
   |
25 |     pub type (unnamed enum at /Users/.../vst3sdk/pluginterfaces/base/funknown.h:189:1) = ::std::ffi::c_int;
   |              ^ expected identifier

It appears the unnamed enum is actually named (unnamed enum at /Users/.../vst3sdk/pluginterfaces/base/funknown.h:189:1) instead of being the empty string.

llvm 16.0.4 (installed with brew)
vst3sdk v3.7.7_build_19
macOS

It turns out this is happening because vst3-bindgen detects unnamed/anonymous declarations by checking if the name was an empty string, but libclang's behavior was changed in version 16 to start returning names like (unnamed enum at ...) instead. Bindgen had to fix the same issue a few months ago: rust-lang/rust-bindgen#2319
