:x for arrays with inferred format

[jonathanpallant]

The manual says you can do this, and it works:

#[derive(defmt::Format)]
struct S { x: u8 }

let x = S { x: 42 };
defmt::info!("{}", x);    // -> INFO S { x: 42 }
defmt::info!("{:x}", x); // -> INFO S { x: 0x2a }

But this does not work, but it probably should:

#[derive(defmt::Format)]
struct S { x: [u8; 2] }

let x = S { x: [42, 255] };
defmt::info!("{}", x);    // -> INFO S { x: [42, 255] }
defmt::info!("{:x}", x); // -> I expect INFO S { x: [0x2a, 0xff] } but it's the same as before

I agree with you and would also expect this to work.
