Resize using only one property

[busybox11]

Hi,
I'm trying to use this webpack module to resize images using a defined height.
Though all of these images don't have the same width and I'd like to keep the original aspect ratio.
I searched in the docs if that was possible but it seems not.
Giving a single property to the resize object (for example, width), errors out saying that the other one is undefined.
Maybe I am mistaken but if that's not the case, could it be possible to integrate an option like this?
Thanks in advance!

set 0 for auto.

resize: { width: 100, height: 0 }
resize: { width: 0, height: 100 }

Thank you!
This should definitely be added to the README.
Going to test this out soon, thanks for your help!
