d91c7dd912 DDS: multiple FP improvements 
- Use of native qfloat16 format
- FP16 and FP32 HDR images are preserved and sRGB Linear profile is set
- Images are always saved as 8-bit so, if valid profile is present the image is converted to sRGB 
- It also fixes (left image) a problem (right image) with HDR images:
