missing linkage to CoreVideo framework

[jbg]

in Cargo.toml:

nokhwa = {
  version = "0.9", optional = true, default-features = false, features = [
    "decoding", "flume", "input-v4l", "input-msmf", "input-avfoundation", "output-threaded"
  ]
}

when running cargo build:

  = note: Undefined symbols for architecture arm64:

          ld: symbol(s) not found for architecture arm64
          clang-11: error: linker command failed with exit code 1 (use -v to see invocation)

I think the fix would just be to add to nokhwa-bindings-macos/build.rs:

println!("cargo:rustc-link-lib=framework=CoreVideo");
