Finish refactor to separate bank_switch and memory_mode
...
There is one failing test, which I expect to fail at this point; that's
because we need to write a read/write map function for the stack and
zero page so that they use aux memory when BANK_ALTZP is on, and main
memory when not.

Some soft switches now require consecutive reads
...
To allow this to work, we had to allow the CPU struct to record what the
last opcode/operand/address were, although in truth we only needed the
last address.

Refactor to remove ram2
...
Both main and auxiliary memory need to keep an extra 4k of memory that
is bank-switchable, so we have changed to store that memory literally
within the main and aux segments.

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.
