Issues on macOS

[palfrey]

Running cargo run on current master (ba77b34) got me the following

    Finished dev [unoptimized + debuginfo] target(s) in 28.01s
     Running `target/debug/oxidator`
[2020-07-06T21:49:44Z ERROR gfx_backend_metal::device] Error compiling the shader CompilationFailed("ImageQueryLod is only supported on MSL 2.2 and up.")
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Other', /Users/palfrey/.cargo/registry/src/github.com-1ecc6299db9ec823/wgpu-native-0.4.3/src/device.rs:1929:13
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Notably, that error isn't anywhere in the codebase for current wgpu-native, so might just be a matter of upgrading that?
