Fix TFTP client attacks without generating event issues

(filename, mode, ignore) = data[2:].split(b"\x00")

This may have 5 parameters, such as [b '/home', b'octet ', b'blksize', b'512 ', b' '], which cannot be ignored by using' ignore '. I don't know if this is caused by the Python version. I am using Python 3.8.10 and 3.12.9, which do not support the' ignore 'keyword. I use the' * _ 'keyword to ignore it. Solved this problem
