Version 9.7.0

IECore

• Fixed potential crash in MeshPrimitiveEvaluator::barycentricPosition() (#475).
• Fixed ConfigLoader to ignore duplicate paths. Note that this may change configuration
  behaviour for malformed paths with duplicates (#474).

IECoreArnold

• Added support for both deformation and transform blur (#473).
• Refactored all Cortex->Arnold conversion functionality into new Algo.h headers,
  removing the old FromCoreConverter based classes. This does represent a compatibilit
  break, but IECoreArnold is in contrib, where no compatibility guarantees exist.
• Fixed warnings relating to the data type of Arnold's visibility parameter, which
  has been changed to AtByte from AtInt.
