Center Image is Not in Foreground

## Version
python: 3.10.7
system: windows 11
qrcode: 7.3.1

## Issue
I am using embedded_image_path to have an image in the center of the QRCode, but all it seems to be doing is putting the image in the background behind the fill_color.  I would expect that when using embedded_image_path the image would be inside a square of unused space for the QRCode.
