Cudavox

Changes:

- Upgraded to CUDA 11.3 release and latest MSVC
- Extra info on unrecognized output formats
- GLM fixes
- File I/O fixes and cleanup

The zip file contains 64-bit (Windows) RELEASE and DEBUG versions of cuda_voxelizer, and a version of viewvox + glut32.dll to view *.binvox models.

Changes:
* Solid voxelization on the CPU now also is properly multi-threaded using OpenMP
* Upgraded to CUDA 11.1 release
* Upgraded compiled binaries to GLM 0.9.9.7
* Extra command-line info on possible output options
* Removed deprecated VS 2015 and VS 2017 projects. Only VS 2019 is supported now if you want to build straight from the *.sln file.

The zip file contains 64-bit (Windows) RELEASE and DEBUG versions of ``cuda_voxelizer``, and a version of ``viewvox`` + ``glut32.dll`` to view *.binvox models.

Changes:
* Solid voxelization now also supported in CPU fallback mode
* Upgraded to Cuda 11.0 Update 1 Release

The zip file contains 64-bit (Windows) RELEASE and DEBUG versions of cuda_voxelizer, and a version of viewvox + glut32.dll to view *.binvox models.

Changes:
* Upgrade to CUDA 11.0 final version
* .obj export code cleanup
* New CMake support (thanks KernelA)

The zip file contains 64-bit (Windows) RELEASE and DEBUG versions of cuda_voxelizer, and a version of viewvox + glut32.dll to view models if you choose to output them as a binvox file.

Changes:
* Add `translate` and `scale` to .binvox output (Related issue: 36) to follow [.binvox spec](https://www.patrickmin.com/binvox/binvox.html)
* Added CPU voxelization timer
* Updated documentation wrt performance

The zip file contains 64-bit (Windows) RELEASE and DEBUG versions of cuda_voxelizer, and a version of viewvox + glut32.dll to view models if you choose to output them as a binvox file.

Changes
- Added experimental solid voxelization (thanks to [conceptclear](https://github.com/conceptclear)). Needs watertight model, incompatible with CPU-based method.
- Changed program parameters ( `-thrust` instead of `-t` for Thrust usage)
- Multi-threaded CPU voxelization support through OpenMP. Should now scale to the amount of cores your system provides.

The zip file contains a 64-bit (Windows) RELEASE and DEBUG versions of `cuda_voxelizer` at the time of writing, and a version of `viewvox` + glut32.dll to view models if you choose to output them as a binvox file.
