Add alignment or left field to image properties

[AntoninHuaut]

Hey thanks you for your library, I have a feature request.

Is your feature request related to a problem? Please describe.
I would like to have the possibility to have the Align field like text on image. Or it's not possible, the right field like the existing left field.

Describe the solution you'd like

image.NewFromBytes(imageBytes, extension.Png, props.Rect{
    Align: align.Right,
})

or

image.NewFromBytes(imageBytes, extension.Png, props.Rect{
    Right: 5,
})

Describe alternatives you've considered
Use the left option, but if the image width is variable, it's not a viable solution, because it can overflow to the right

Additional context
I'm using :

• row
  • col 6
    • text
  • col 6
    • text or image

Currently is possible to put the image in any local of a col. As you can see here: https://maroto.io/#/v2/features/image?id=image

[johnfercher]

props.Rect{
        Center:  false,
        Percent: 80,
        Top:     5,
        Left:    10, // move here
}

My image can be different, with a variable width, but I found something like that:

imgWidth := float64(img.Width) * lineHeight / imgHeight
...
props.Rect {
  Left: 41 - imgWidth
}

Just a random magic value '41', but I tried different images and it's always well aligned to the right. It does the job
