added

4.2.other) data_src util faceset metadata save.bat
	saves metadata of data_src\aligned\ faces into data_src\aligned\meta.dat

4.2.other) data_src util faceset metadata restore.bat
	restore metadata from 'meta.dat' to images
	if image size different from original, then it will be automatically resized

You can greatly enhance face details of src faceset by using Topaz Gigapixel software.
example https://i.imgur.com/Gwee99L.jpg
Example of workflow:
1) run 'data_src util faceset metadata save.bat'
2) launch Topaz Gigapixel
3) open 'data_src\aligned\' and select all images
4) set output folder to 'data_src\aligned_topaz' (create folder in save dialog)
5) set settings as on screenshot https://i.imgur.com/kAVWMQG.jpg
	you can choose 2x, 4x, or 6x upscale rate
6) start process images and wait full process
7) rename folders:
	data_src\aligned        ->  data_src\aligned_original
	data_src\aligned_topaz  ->  data_src\aligned
8) copy 'data_src\aligned_original\meta.dat' to 'data_src\aligned\'
9) run 'data_src util faceset metadata restore.bat'
	images will be downscaled back to original size (256x256) preserving details
	metadata will be restored
10) now your new enhanced faceset is ready to use !
