gamev9.2 fevertime table gen.py

# v9 includes 0 in feverboard
# which is the MAIN difference between other boards
# this code is incompatible with v8

# game v9.1 table gen
# nhr is now in reverse for faster overall generation

# game v9.2 gen
# id system changed
# 15,15,15,...,15  is now id 0

# made with love by nope ❤
