Decode data where pixels with lower column values are stored in the lower-order bits of the bytes (TIFF FillOrder is LSB2MSB). Parameters: data: Data to be bit-reversed. If bytes type, a new bit-reversed bytes is returned. NumPy arrays are bit-reversed in-place. out: Output buffer (currently unused). _bitorder: Internal caching parameter (not for public use).
