# -------------------------------------
# data is aligned to nearest 0x80
# header size is normally 0x7C aka
# 0x80 aligned, minus 4
# (doesn't include 4 bytes for the header size)
# then data size starting at [header_size + 4]
# then number of files, read 12 bytes each and seek
# 12 = hash(?), start pos, end pos (from start of file)
# then just seek to [header_size + 4] and extract files

faster, checks for magic bytes
from zlib import decompress
from io import BytesIO
import sys
data = open(sys.argv[1], "rb").read()
#use this without making giant range() array
size = len(data) - 1
#better than a string ?
output = BytesIO()
#get byte 0 for the loop
