ScaleIntensityRangePercentile bug

[heyufan1995]

Describe the bug
In ScaleIntensityRangePercentile, the output is converted back to input dtype and ignored the dtype input. If input is uint8, the scaled image is wrong.

MONAI/monai/transforms/intensity/array.py

Line 1414 in 59a7211

return convert_to_dst_type(img_t, dst=img)[0]

In ScaleIntensityRange, the implementation is correct

MONAI/monai/transforms/intensity/array.py

Line 1006 in 59a7211

ret: NdarrayOrTensor = convert_data_type(img, dtype=dtype)[0]
