// LZ4_NO_SHUFFLE is READ-ONLY: HDF5 filter 32004, plain LZ4 with no bit shuffle, written by DECTRIS
// Eiger firmware 1.x. Nothing here produces it. It is last so the values of the others do not move -
// the enum crosses the CBOR stream.
//
// CBF_BYTE_OFFSET is READ-ONLY too, and never leaves the process: it is how the miniCBF reader hands
// over a frame as the file stores it, so that the GPU path can upload those bytes and decode them on
// the device. The image's mode is what it decodes to (Int32).
