Description
It is a proposal of the function to implement.
I want to add the function to resize and insert an image fit to the cell.
Resize to the size of a single cell or merged cell without changing the aspect ratio of the original image.

ex.) xlsx.AddPicture("Sheet1", "A2", "./image1.jpg", {"autofit": true})
I would like to implement such a function. What do you think?

It is an image when the image is inserted.

I resolve conflicts and perform a manual merge.
