• Improved fine detail preservation
• Added the cleanAux filter parameter for further improving quality when the
  auxiliary feature (albedo, normal) images are noise-free
• Added support for denoising auxiliary feature images, which can be used
  together with the new cleanAux parameter for improving quality when the
  auxiliary images are noisy (recommended for final frame denoising)
• Normals are expected to be in the [-1, 1] range (but still do not have to
  be normalized)
• Added the oidnUpdateFilterData function which must be called when the
  contents of an opaque data parameter bound to a filter (e.g. weights) has
  been changed after committing the filter
• Added the oidnRemoveFilterImage and oidnRemoveFilterData functions for
  removing previously set image and opaque data parameters of filters
• Reduced the overhead of oidnCommitFilter to zero in some cases (e.g. when
  changing already set image buffers/pointers or the inputScale parameter)
• Reduced filter memory consumption by about 35%
• Reduced total memory consumption significantly when using multiple filters
  that belong to the same device
• Reduced the default maximum memory consumption to 3000 MB
• Added the OIDN_FILTER_RT and OIDN_FILTER_RTLIGHTMAP CMake options for
  excluding the trained filter weights from the build to significantly
  decrease its size
• Fixed detection of static TBB builds on Windows
• Fixed compile error when using future glibc versions
• Added oidnBenchmark option for setting custom resolutions
• Upgraded to oneTBB 2021.2.0 in the official binaries
