Description

Since version `1.5.6` draco wasm loading fails on iPhone 6 IOS 12.5.5 with following error:

```
failed to asynchronously prepare wasm: Error:
WebAssembly.Module doesn't parse at byte 58: invalid opcode 192, in function at index 16
```

I've tested previous versions and noticed that `1.5.1` fails to load with the same error, while other versions from `1.4.1` to `1.5.5` load properly without no issues.

All tested files were loaded from cdn https://www.gstatic.com/draco/versioned/decoders/1.*.*/
