Paper Tape Format Disassembler

I have extended my cross-assembler with a built-in disassembler that can directly read from paper tape format (and a few other formats). For example, the following test assembly program

      .org $0200
      ldx #100
loop  dex
      bne loop

is, under option -P, assembled into paper tape format (text representation):


Option -dP activates the disassembler on paper tape format represented as text, which disassembles the format above back to:

$0200 a2 64  ldx #$64
$0202 ca     dex
$0203 d0 fd  bne $0202
$0205 00     brk
