Direction array different with image-io round trip

[PaulHax]

While using the @itk-wasm/image-io typescript "demo webpage" the direction array of an input image is different than the output image.

Steps

1. Using an image with non-trivial direction array.
2. On image-io test webpage modified to console.log(image.direction), run readImage, note direction array.
3. On writeImage, upload image, serializedImage set to out.nii, "Run".
4. With readImage, load out.nii, note direction array. Expect array to be similar to input image direction.

With this image:
labelmap-nii.zip

Input direction array is
"0": 1, "1": -1.9901096072372604e-10, "2": 4.9618989722737154e-11, "3": 2.0510340648094427e-10, "4": 0.9702957283983676, "5": -0.24192188394878414, "6": 1.3830191008187543e-17, "7": 0.2419218870873018, "8": 0.970295729180888

After writing to .nii or .nrrd, readImage gives direction array
"0": 1, "1": 2.051034067230632e-10, "2": 1.3704920054353578e-17, "3": -1.9901096048879907e-10, "4": 0.9702957283983676, "5": 0.24192188394878414, "6": 4.9618989472755004e-11, "7": -0.2419218870873018, "8": 0.970295729180888

Indexes 5 and 7 are negated.
