As part of tokenization for (de)parsing, we need to do something like a
disassembly, but is is really a little different.
Disassembly, strictly speaking, is done by the xdis module now.
What "ingestion" does is massage the instruction tokens to a form that is
more amenable for parsing.
In sum, ingestion is different than disassembly, although disassembly is
generally the first part of ingestion.
disas.py:
- disassembles *all* code objects found
scanner*.py:
- no longer need to pass in version numbers; this
is obtained from the class name
- no longer pass in opcodes; this is done at
initialization from the scanner name
- all Pythoin 3 scanners support native disassembly
