Update to latest upstream release:

• Better slice timing detection see 311 and 322.
• Ignores Philips non-image DICOM files.
• 2D slices from a 3D CT series will be merged as a single volume, even if the X-Ray exposure varies between slices. MRI scans are not influenced. To elicit the old behavior, select -m n.
• Less verbose warning, error and messages generated.
• Ability to convert DICOM images to NRRD format (use -e y), gradient formulas by Tashrif Billah.
• Improved CT tilted gantry conversion
