neraulgraphics 0.2.0

The renderer is now a package you can call from Python or C++.

Added

• Python package: pip install, then import neraulgraphics. Renderer.render()
  returns a (height, width, 3) uint8 numpy array. Vectors are plain tuples,
  lists or numpy arrays. Bad input raises ValueError; CUDA failures raise
  neraulgraphics.CudaError. Type stubs included.
• Linux wheels for Python 3.10 and later that need only the NVIDIA driver, not
  the CUDA toolkit, built for every GPU generation from Turing to Blackwell.
• neraulgraphics/version.h, generated from the version in CMakeLists.txt.
• C++ tests, run with ctest.

Changed

• Renamed everything to neraulgraphics: find_package(neraulgraphics), the
  neraulgraphics::core target, #include <neraulgraphics/renderer.h> and
  namespace neraulgraphics. The viewer is now neraulgraphics-viewer.
• The public headers no longer include any CUDA header. Vectors are
  neraulgraphics::Vec3, and make_camera is computed inside the library, so
  cameras no longer depend on the caller's floating point flags.
• The Renderer floor argument is optional; the default is no floor.
