3.1.8.1.5 Simplified Run-Length (SRL)
The Simplified Run-Length (SRL) Encoder uses the same zero run-length engine as the RLGR entropy encoder ([MS-RDPRFX] section 3.1.8.1.7). However, it differs when encoding nonzero elements, because these elements are unary-encoded (there is no Golomb-Rice coding). An extra zero byte is always emitted after the last SRL byte.
