Function format 

pub(crate) fn format(blob: &[u8], crc: u16) -> String

Render a 128-byte blob as an annotated text document.

The annotation lists every byte alongside the field it belongs to and flags the value (factory-area, lock state, slot configuration, etc.). The CRC value passed in is included at the bottom and is meant to be the CRC of the writable portion (bytes 16-127), computed by the caller.
