Banner horizontal position on landscape

[Tobertet]

Is your feature request related to a problem? Please describe.
I see that on landscape, the banner is almost always at the bottom lower left corner. However, I'd like it to be at the right left corner.

Describe the solution you'd like
Add options BannerAdPosition.BOTTOM_LEFT, BannerAdPosition.BOTTOM_RIGHT

Describe alternatives you've considered
I could use margin depending on the phone size, but the problem is the banner is not always placed in the bottom left, so it is inconsistent.

Currently, we don’t provide a BOTTOM_LEFT option. The available positions are only TOP_CENTER, CENTER, or BOTTOM_CENTER.

Since the banner takes up 100% of the width in landscape mode, we haven’t considered options for left or right alignment.
