num_ref are represented using golomb and may be very large.
BitstreamReader is generally resilent to many consenquites fail reads, but not when number of reads comparable to int limit.
This change address the issue in two ways, either one is enough, but both are helpful in their own way:
H264 parser now fails faster when number of references is too large.
BitstreamReader now is resilent to unlimited number of fail reads.

Unlike ReadBits, ConsumeBits doesn't limit number of bits it may advance,
and thus should work when that number is close to the integer limit

With intent to replace BitBuffer.
This version is optimised for binary size and readability of the parsers
at the cost of slower parsing of invalid bitstreams
