Second part to fixing the 10th style SQ-INIT error. This has
cross-impact on the kind of security data the game expects.
Therefore, we need to expose the IO board type and make it
configurable like the security data for the different game
versions.
More details explained in a dev journal entry to following
in one of the next commits.
Used for dumping firmware, only. C02 and D01 boards only differ
in the FPGA firmware written to the board on boot up. This doesn't
matter for emulation, but when using a real IO board with
iidxio-ezusb.dll, a different FPGA firmware is required to be
flashed in order to get working turntables, top unit lights etc
