Although NGByteBuffer is defined to be a stream, it is usually not used as
such. Instead most parsers implemented using NGByteBuffer will only call
-la: and -consume.
The stream interface is provided to read large blocks with a known length. Eg
if you have a structure that prefixes some data with the data's length, you
can first parse the length and then call -safeReadBytes:count: to read the
content.
Note that -readByte and -la: return -1 on EOF.
