Merged read/write commands in HF MFU.

Since the dump and info commands is almost there with all kinds of support,  I decided to fix the read and write commands.

The new commands; 

HF MFU RDBL
-------------------------------------------------------------------------------------
Read a block and print. It autodetects card type.

Usage:  hf mfu rdbl h l b <block number> k <key>

  Options:
  h       : this help
  b <no>  : block to read
  k <key> : key for authentication [UL-C 16bytes, EV1/NTAG 4bytes]
  l       : swap entered key's endianness

  sample  : hf mfu rdbl b 0
          : hf mfu rdbl b 0 k 00112233445566778899AABBCCDDEEFF
          : hf mfu rdbl b 0 k 11223344

HF MFU WRBL
------------------------------------------------------------------------------------------
Usage:  hf mfu wrbl b <block number> d <data> k <key> l
  Options:
  h        : this help
  b <no>   : block to write
  d <data> : [block data] - (8 hex symbols)
  k <key>  : key for authentication [UL-C 16bytes, EV1/NTAG 4bytes]
  l        : swap entered key's endianness

  sample   : hf mfu wrbl b 0 d 01020304
           : hf mfu wrbl b 0 d 01020304 k 11223344

Re: Merged read/write commands in HF MFU.

I think there is a bug in the read commannd:

proxmark3> hf mfu rdbl l b 5 
Block: 0 (0x00) [ 04 01 02 8f ]         
proxmark3>

It always keeps to read block0 instead of the specified one.

SORRY - I WAS WRONG - I WAS USING Marshmellow .exe ! With your one ice it is working !

pm3 --> hf mfu rdbl l b 1 
Block: 1 (0x01) [ AA 16 3C 81 ]         
pm3 -->
pm3 --> hf mfu rdbl l b 5 
Block: 5 (0x05) [ 00 00 00 00 ]         
pm3 -->
pm3 --> hf mfu rdbl l b 5 
Block: 5 (0x05) [ 00 00 00 00 ]         
pm3 -->
pm3 --> hf mfu rdbl l b 3 
iso14443a card select failed         
pm3 -->
pm3 --> hf mfu rdbl l b 3 
iso14443a card select failed         
pm3 -->
pm3 --> hf mfu rdbl l b 3 
Block: 3 (0x03) [ E1 10 6D 00 ]         
pm3 -->

Re: Merged read/write commands in HF MFU.

good,   you only need the "L"  together with a "K 11223344"  authentication.
The  "L" option swaps the endianess of the key if you use it.

"hf mfu rdbl b 1 k 11223344"      uses key: 11223344
"hf mfu rdbl b 1 k 11223344 l"    uses key: 44332211
