Fluid Sizing with vheight and vwidth

The WelcomeAdBannerView supports fluid sizing, allowing it to adapt to the available space in the parent collection view or view controller. To achieve this, provide the desired size through the vheight and vwidth keywords in the ad configuration:

• vheight: Specifies the height of the banner in points. This should match the available height in the parent view.
• vwidth: Specifies the width of the banner in points. This should match the available width in the parent view.

These keywords ensure the banner expands to fill the provided dimensions, maintaining a responsive layout.
