Add memory injection to 6502; main memory in apple2
...
Note that memory _is_ now managed in apple2, and _not_ in mos6502.

Change memory_mode -> bank_switch
...
This also changes the concept of the field; bank_switch is a collection
of bit flags now.

We can no longer assume PC increments during address handling
...
This change required a number of consequent changes to assumptions we'd
made, and I'm not 100% confident we have things right at this point in
time.

Added a "fix" to JSR test.
...
It's really wrong, because we _should_ be storing PC + 2 in the stack.
And software's definitely gonna bork when we try emulating them, because
they will invariably inspect the stack and assume that's what we have in
there.
But the proper fix is to not actually do next_byte(), and to never
advance PC outside of the execute function. But that's a bigger change
than I want to do at this specific moment.
So, in the meantime, you have me prattling on in a commit message. Lucky
you!

We have a raft of changes here...
...
1. In some cases we corrected little-endian issues.
2. In others, we need to correct expected output to account for PC,
cycles and hex dumps.

Change 16-bit references to respect little-endianness
...
As the Apple II (or rather the 6502 chip) is little-endian, meaning the
least significant byte is the first byte you read going forward, rather
than the last byte.

Small bug in the jump label code for IND

This also required a rethink on some core functions which now needed to
know about the memory segment; and further changes in the unit-testing
code on the disassembly suite was also necessary.
