Verify available bits in bit stream
The methods to read n bits from the huffman stream are not correctly
checking that the bits are available. This means, we'll end up reading
0 bits due to the checks below and pretend like the read worked.
This Cl adds the check that we are not at the end of the bit buffer
before attempting the bit read.
