41bf01d035 Convert Ophis to Python 3.
Most of the work is handled by 2to3, but there's a few extra tricks
needed to finish the job, mostly about picking the right bits to be
Unicode and the right bits to be bytes.

778fbf7e2c Improved Atari 2600 example programs
Add the color test program as a sample program. Also update
the hi_stella example so that it runs properly when run in a Harmony
cartridge.

c3d48da59d Fix issue with branches in listfiles.
Due to whitespace vagaries, etc., a sample correct output has been
added to the test case files, but isn't directly checked as part
of verification.

d3772587da Include a .cbmfloat pragma to make creating data simpler
Due to the usual vagaries of floating point, these are not completely
perfect, but for "human-scale" numbers it will be OK.

70f93b22eb Rework label map collection
This uses a pass to interrogate the system for locations, then dumps
those out instead. It handles includes, anonymous labels, and basic
macros, but it does so in a somewhat ugly way. This data can be
readily abbreviated and should also be re-sorted.

e5ac21f0f9 Second attempt at implementation of the BBXn instructions for Rockwell 65c02 chips.
Reliable technical documentation for how these instructions are decoded is a
little thin on the ground online, so some of this implementation is still
speculative.

cc9acf3ce4 Bugfix: Let Collapse Pass reverse collapses

23700276a6 Introduce wide-mode override opcodes.
This solves the --no-collapse problem by letting you force
Absolute mode on an instruction by instruction bases, which is
usually going to be what you want anyway.

4891849e4a Pass control command line options.
It turns out that --enable-collapse is fundamentally misguided. We'll
need a better solution for that. --no-branch-extension looks pretty good.
