Adding Error Check for f_code Parameters

In MPEG1, the valid range for the forward and backward f_code parameters
is [1, 7]. Adding a check to enforce this. Without the check, the value
could be 0. We read (f_code - 1) bits from the stream and reading a
negative number of bits from the stream is undefined.
