Paul Molloy c6a68c679f Adding EXP0_PULLUP_TEST should probably verify pullup on EXP0 provides
logic 1 if relying on it.  Seems to work fine on NES discrete and
INLXO-ROM boards where planning to utilize it.  SNES can't pull up due to
pulldown and original famicom cart can't either perhaps because of
EXP6 EXP FF output being too much of a load..?

Paul Molloy 7d00145431 Big step in confirmation of pin manipulations working on kazzo.
Able to read PRG-ROM flash chip's manf and device ID from commandline.

New dictionaries io and nes along with firmware files to support.
now have io_reset, nes_init, and snes_init io.c functions
nes.c functions including discrete_exp0_prgrom_wr and emulate_nes_cpu_rd.

New dictionary.c/.h for host to make dictionary calls easier including
setting proper return data lengths based on opcode.

adding nop command to pinport.h
