Wouldn't flag operand-less undocumented DD/FD opcodes.
DD/FD followed by DD/FD is an undocumented NOP.

Should now produce sensible output for every random byte stream.

before:
0000 - DD 37            SCF
0002 - DD FD
0004 - DD               NOP*
0005 - ED 45            RETN
0007 - DD 11 F1 0C      LD*     DE,0CF1

now:
0000 - DD 37            SCF*
0002 - DD               NOP*
0003 - FD               NOP*
0004 - DD               NOP*
0005 - ED 45            RETN
0007 - DD 11 F1 0C      LD*     DE,0CF1

Bloody undocumented instructions... but who am I to complain,
I started it...
I needed to lookup that word online ;-)

Output numbers in assembler hex notation to make it easier to convert
disassembler output into something that the assembler accepts.
simdis: fix undocumented opcode disassembly and increase assemblability of output
simice: use from,to arguments for dump and list
