The last segment of chunksize will be in wrong length(188-sync_offset) if there's a resync

[cnrting]

for example:
chunksize=8
sync_offset=40
these code here:

        if sync_offset != 0:
            print('Resync')
            data = data[sync_offset:]

the data's length will change to 188*8-40 and will cause unpack error when unpack the last segment of chunksize cause it's length has only 148 bytes
