feature request: direct cast to 16bit as option in nabu config

Would be possible to add an output option to directly cast the reconstructed volumes to 16bit without ever saving the float32 volumes? Maybe even in Tomwer. Min/max as manual input or automatic and stored somewhere. The float32 images give little advantage when our cameras often produce max 16bit (edge, only 10bit for Dimax/Photron) anyways and are much more difficult to handle for image processing downstream because of their size. Especially for time resolved XTM with tens or even hundreds of scans such a feature would also avoid producing large and then duplicate data that potentially even goes unnecessarily to tape. I understand too little to build this myself. At the moment I am limited to hacking the config file.
