Identifying Slice Timing Order from DICOM and nifti

@DasDominus if you have the DICOM files, you could try the philips_order.py script created by @yarikoptic. This clearly works for some but not all Philips DICOM images. My best sense is it worked once upon a time when serial slice acquisition (non-multiband) and reconstruction was used. @sandeepganji might also have some tips.
