Update Coding Style for ITK

Engineering

With commit STYLE: Enforce ITK style defined by .clang-format, the formatting of the function body of ImageRegionRange::begin() has changed from:

Before the commit:

return iterator
{
  m_BufferBegin + Self::ComputeOffset(m_OffsetTable, m_BufferedRegionIndex, m_IterationRegionIndex),
  m_OffsetTable,
  OffsetType(),
  m_IterationRegionSize
};

To:

After the commit:

return iterator{ m_BufferBegin + Self::ComputeOffset(m_OffsetTable, m_BufferedRegionIndex, endRegionIndex),
                 m_OffsetTable,
                 iterationOffset,
                 m_IterationRegionSize };

See https://github.com/InsightSoftwareConsortium/ITK/blob/master/Modules/Core/Common/include/itkImageRegionRange.h#L377

Was this change intended? Personally I would prefer to have a pair of matching curly braces { and } on either the same line of code, or the same column (one exactly below the other). As it was before the commit.
