Adaptive Banner support

[edscodeblenders]

Hello,

Once GMA version 20.0.0 (Android) and 8.0.0 (iOS) are released (they're announced to be released on early 2021), Smart Banners will be deprecated, and Adaptive Banner will be the way to go.

At the moment the Admob plugin for Flutter doesn't support Adaptive Banners. Do you have plans to start supporting them? When can we expect them to be available?

Thanks.
