Broken versions

• 0.3.5 | CRITICAL: 0.3.5 can produce invalid bitstreams and does not decode valid bitstreams The fast code path (via TreeToLookupTable) does not seem to be exactly equivalent to the generic path, causing valid files to be undecodable and the encoder to produce invalid files. (https://gitlab.com/wg1/jpeg-xl/-/issues/191#note_537511533)
• 0.3.1 | files generated with v0.3.1 that contain an embedded ICC that uses the affected tag (XYZ) are invalid (https://gitlab.com/wg1/jpeg-xl/-/issues/149)
