RunLengthDecode filter (PDF 32000-1:2008 §7.4.5). Decompresses byte-oriented run-length encoded data.
A truncated stream is not an error: a missing EOD marker (128), a run marker with no byte after it, and a literal run reaching past the end of the data all end the decode and return the bytes recovered so far.
