Cycles: Add denoising option to the Cycles Standalone executable

To use it, call it with "./cycles --denoise --samples <sample number> --output <denoised_file.png> <rendered_image.exr>".
You need to enter the sample number that the image was rendered with - others will work as well, but might produce artifacts.
The input image can be generated by rendering with "Keep denoising data" enabled (denoising itself isn't needed) and saving the result as Multilayer EXR.

For now, this is mainly useful for quicker testing without re-rendering and profiling, not so much for regular users.
However, the next step will be to implement inter-frame denoising for animations, which will provide a significant quality boost.
