Added aux memory and 80 column card stubs ...
...
... just enough to fool prodos that there's only 64k of RAM and no
80 column card.

Refactored memory read/write to MMU
...
This required moving some common things in a new package to resolve a circular
dependency between cpu <=> mmu.

Replaced MemoryMap with an PageTable array

There was no good reason to be using a map when an array lookup would have
done nicely.

Added MMU and WIP rudimentary apple //e boot test
...
Basic memory management has been implemented since $c100-$cfff needs flipping
with soft switches during Apple //e boot. All memory reads & writes now go
through the MMU. Memory is also dynamically allocated and associated with the
CPU state.
