P: Revert HDR and Pano Merges to previous DNG format

As far as I can reproduce it, since LrC 13.x HDR, Panorama and HDR Panorama mergers result in Lossy Compressed DNGs. That's a total no go.

Dear Adobe, please revert this instanly by an over night fix or give us at least an easy to find checkbox in the settings to decide that by ourselves.

We don't need Adobe making that kind of decisions for us creatives, that's anti creative.
