Decompress an SCB encoded input stream. SCB stands for String Control Byte, an SNA text compression scheme. In its basic form, it compresses repeated characters. The compaction feature uses a table to assign 4-bit codes for up to 16 frequent bytes. Each unused 4-bit code forms the 4 high bits of 16 8-bit codes.
