     Image name should be the faction + monster ID. Model `FFMM`. So an imperial
     spearman is named `0001` and an arch wizard is named `0701`.
     Attribution template is sent to ATTR.txt for convenience

+* units.py
+  * Based in "ready-units" folder, using semi-qualified name (e.g. 1002 - 1 star,
+    unit 2; The "10" prefix and 0x suffix is not needed). Resizes image to 640x960
+    and finds a face, which is then centered and a square is produced, then the
+    three image slices are made. Accepts PNG and JPG input, output is Webp.
+    If there is a image with same name but "sq_" prefix, it's used instead of face
+    detection tool. The output is saved in square/ and unit/ subfolder
+  * Structure:
+    ready-units/
+        unit/
+        square/
+        base/ ← Save your images here
