OptionalbufferOptionalbufferHow many chunks behind latest request to store in buffer.
This is ignored if the ChunkSource supports getChunk() function.
After processing an Interest requesting segment i, subsequent Interests requesting
segment before i - bufferBehind cannot be answered.
A larger number or even Infinity allows answering Interests requesting early segments,
at the cost of buffering many generated packets in memory.
A smaller number reduces memory usage, at the risk of not being able to answer some Interests,
which would become a problem in the presence of multiple consumers.
