Function parse_set_puk 

pub fn parse_set_puk(
    payload: &[u8],
) -> Result<([u8; 8], [u8; 8], [u8; 32]), PayloadError>

Parse the payload of CommandOpcode::SetPuk.

Layout: old_puk (8) || new_puk (8) || io_key (32). Authentication is via the PIN session (the caller proved knowledge of the current PIN earlier); old_puk is kept in the payload for forward compatibility with a defence-in-depth pass that would re-verify the old PUK on the chip before accepting the new one.

Returns (old_puk, new_puk, io_key).

Errors
