Fix rare bug: right shift by a negative # of bits
Under very rare circumstances, decompressing specific corrupt JPEG
images would create a situation whereby GET_BITS(1) was invoked
from within HUFF_DECODE_FAST() when bits_left=0. This produced a right
shift by a negative number of bits, which is undefined in C.
