FIX; the "L" optional parameter for swapping endianess on used authentication key...

"HF MFU INFO"
"HF MFU DUMP"
"HF MFU RDBL"
"HF MFU WRBL"

CHG;  I commented away the option to add the key to the dump, since it is not written in big-endian, like the data is on ULC. This needs to be addressed before it comes back. I like the idea of having keys inside the dumps on the correct places.
