Support for Saving in OpenEXR Format

Hello,

I think it would be nice to have the option of saving my final HDR images in OpenEXR format in future versions of EHDR. This file format seems to have a lot going for it. It has a wider color gamut (1 Billion colors vs. 16 million for the Radiance HDR file format) and covers all of the visible color spectrum; and has a pixel depth of 48 bits vs. 24 for Radiance HDR. The biggest drawback to the Radiance format is limited color range, which the OpenEXR format makes up for. The Radiance file format is getting a bit long in the tooth as well. It was created in 1987.
