Add divider
...
Adds a 16x16 divider to go with the multiplier.
The divider is a single stage with no pipelining, which works at the
slow 2MHz frequency. Doing this lowers the maximum clock frequency to 5.
This is acceptable for now but means that the cpu can't be run at 14,
which is the maximum frequency.

Add multiplier
...
Add 16x16 multiplier.
Pretty simple. Address 0-1 is multipled by address 2-3 and the result is
in address 4-7, all little endian of course.

Add LED module and address decoding; disable LA
...
The Logic analyzer isn't that useful anyway since it does not track
rising and falling edges.
