art_decode_dict.py

# For standard font in art library it the third line of the number outpts are all unique
# Therefore it is enough to check only the third line to be able to decode the string.
# The only caveat is with 1 and 0 the identifying string of 1 is a subset ob identifying string of 0
# To get around it we just need to check for a matching 0 first, if it mathces we definately know its not 1 other wise we check for 1
# There is also the case of 4 which has a identifying string length of 8 which is more than the standard for all other numbers except 1
# This file stores the mapping from each identifying string to the number and the reverse mapping too.
