The File Output node doesn't provide an option to save byte formats like PNG in a space that is not sRGB. This is problematic for data images like normal maps, which need to be saved as non-color. This patch adds a Color Space option to the File Output node to allows users to override the assumed color space. This also adds a new global Save As Render option that is used if Use Node Format is enabled. Pull Request: https://projects.blender.org/blender/blender/pulls/124238
