properly distinguishes between intermediate reads which are part of writes,
and ordinary reads. In the former case, only a read which has a different
address than a write is flagged as an error; intermediate reads acting on
the same address as the corresponding write are considered normal, and won't
trigger a break.

breaks to test whether an illegal read to the write port of cartridge
RAM has occurred. It can be used as follows:
breakif {_rwport == 100} // break if read was done at wport address 100
breakif {_rwport} // break if read was done at *any* wport address
This currently works for all extended RAM carts that worked before.
Specifically, 4A50, DPC, AR and possibly several others aren't supported
yet. More testing is required.
Renamed CartFASC and CartMB to CartFA and CartF0, respectively. This
naming now matches that used in other emulators.
CartMC now properly handles read from write port, by using random
values instead of just zero. However, no test ROMs are available for
this scheme, so there may still be issues.
