Upgrading pybind11 and software packages versions

Features:

• Introducing Raspberry Pi 4 support
  • USE_EGL_DRM=ON needs to be supplied to cmake when compiling for Raspberry Pi 4
  • For Raspberry Pi prior to 4 series, the cmake options become USE_EGL=ON and USE_BRCM_LIBS=ON
• Updating X2 neural net and implementation
  • 32.64 dB PSNR on DIV2K validation set, previously 32.57 dB
  • Reducing register pressure in shaders
• Introducing dog classification neural net featuring inference with NNets
  • 72% top-1 validation accuracy on 120-class subset of ILSVRC 2012 containing images of dogs with a model of 225k parameters
  • Introducing a piecewise sigmoid-like activation suitable for the shader-based inference implementation
• Supporting clipped ReLU activation
• Introducing GLSL dialect for better compatibility with different GPUs
  • Automatically transforms the shader code into GLSL ES 2.0, GLSL ES 3.1 or GLSL 1.3 depending on the OpenGL version supported by the GPU
• Fixing bugs and introducing new ones
