com.fasterxml.util.membuf.StreamyBytesMemBuffer
Byte-valued {@link StreamyMemBuffer}: memory buffer that stores sequence of bytes without preserving boundaries between different appends (that is, contents of a single append can be retrieved using multiple reads, as well as contents of multiple appends can be retrieved with a single read)
