Maybe I'm using it wrong (thought it's hard to tell because there's not really any documentation), but `save_image()` always gives me this error: thread 'main' panicked at 'Error message: Unsupported operation/parameter option', C:\Users\Tim\.cargo\registry\src\git.colasdn.top-1ecc6299db9ec823\arrayfire-3.4.2\src\error.rs:66 I've tried PNG, JPEG, f32 arrays, u8, 3D, 2D, etc. It really needs better error reporting too.
