Rewrite status checks with macros
...
This also forces the result of operations to be considered purely as
8-bit results in _some_ cases, but not in others. We were missing some
times when an overflow is the expected behavior; because SET_RESULT()
and mos6502_modify_status() use ints, this overflow was not properly
observed.

Formerly "BAD" instructions are now forms of NOPs
...
But weird forms. In most cases they basically are NOPs, except with
different opcodes. In other cases, we call them NP2 and NP3s, and do so
because they consume 2 or 3 bytes respectively (vs. just 1 with NOP).
We had to teach some arcane magic to the emulator for this to work. We
may want to refactor to decouple the number of bytes consumed from the
address mode.

Add new BIM instruction (BIt imMediate mode)
...
This is not a real instruction in the 65c02 processor; I invented it for
the sole purpose of handling the specialized logic that is performed by
BIT in IMM mode. To be fair--I can imagine this really _was_ implemented
as a "separate" instruction on the chip! But I don't know that for sure.

Pass in sector table for logical-physical orders
...
We were not encoding data properly, because in DOS 3.3 and ProDOS,
sectors must be interleaved on disk media (whereas in the original image
form, data is laid out in a linear fashion).
This solves a bug where we erroneously encountered a "bad" opcode (a7)
in the program code.
