Implement better downscaler #1
Description
The following image has been created with DeepDrill 3.0. A 4K map file was computed and downscaled to 1920 x 1080 afterwards:
./deepdrill -o seahorse1.map seahorse1.ini 4K.ini
./deepdrill -o seahorse1_4K.jpg seahorse1.map
Here is the same image, downscaled from 4K to 1920 x 1080 with the macOS preview app (much better):
