Added a code generator for a simple interactive HTML image viewer. Supports Python and .NET, standalone and Jupyter.

Support writing most image formats to memory

• Supports loading TIFF (32 bit float and 8/16/32 bit uint) via TinyDNGLoader
• Adds tev support to Python by adapting Tomas Iser's gist
• Reinhard and ACES tonemapping support

Fixes a memory leak in the denoiser (C#) and a missing file in the Python package.

Workaround for syoyo/tinyexr#160
Switch to ZIP compression when writing .exr images.

Note: to load a PIZ compressed .exr correctly, you may have to use OpenEXR to re-encode with one of the other supported encodings.

Changes since 0.7.0

• Added XML documentation for all public classes and methods
