Version 1.5 improvements

The board for sale here is the new OtterX 1.5 design which has the following changes:

No more "bodge board". Cartridges work flawlessly on this board design without needing a special board and bodge wires.
IEC port removed. The IEC port was used by less than 5% of customers and its location put it in conflict with the upcoming digital video output board. A 6 pin IDC-style box header is provided to allow a passive connection to an IEC "dongle" to add this functionality back in.
TO-92 transistor footprints changed to new footprint with wider spacing. Microscopic solder bridges between transistor pins was the #1 cause of build issues with the original OtterX. This change should remove this issue entirely.
NES 3&4 ports have moved to a 6-pin IDC-style box header. A "dongle" to make these easily available is coming soon.
TVS diode footprints have been corrected so that bidirectional or unidirectional ESD protection diodes will work.
Cartridges with a shell now fit the card edge connector without conflicting with the memory expansion module.
Memory expansion module has been redesigned to provide space for cartridges and a standoff to ensure that the memory expansion doesn't short contacts against the battery clip below it.
