Description
This is a rework of #2589 for V4 that generalizes the segment error handling allowing us to specify rules during identification.
PngCrcChunkHandlingfromPngDecoderOptionsSegmentIntegrityHandlingtoDecoderOptionsPNG is currently the only format that uses these properties, but others can be migrated when required.
