Bug reported here: https://github.com/flyimg/flyimg/discussions/598

Steps to reproduce
Open the demo.
Request an image with a different aspect ratio using both width and height,
https://demo.flyimg.io/upload/w_200,h_300,par_1/https://flyimg.io/demo-images/Citroen-DS.jpg
or
https://demo.flyimg.io/upload/w_200,h_300,par_0/https://flyimg.io/demo-images/Citroen-DS.jpg.
Actual behavior
Returned image size is ~200x173, preserving the original aspect ratio.
Changing par between 0 and 1 has no visible effect.
Expected behavior
par=1 (default): preserve aspect ratio (current behavior).
par=0: do not preserve aspect ratio; stretch image to exactly the requested w×h (e.g. 200x300).
