Detect native fluid ads by app events on Android

[przemyslawzalewski]

Even for native/fluid ads, the Android ads library reports them as plain banner ads. This is preventing the layout of the ad properly as the 320_50_mb is a valid banner size. With this PR, the fluid/native ad is detected anytime the ad sends any custom ad event.

The issue is deep within the Google Ads library, affecting others as well, for example, sbugert/react-native-admob#206.

Hi there 👋 - I'm part of a group that is also implementing ads in a different module - https://github.com/invertase/react-native-google-mobile-ads (reborn recently/finally from the official google firebase react-native repo @react-native-firebase/admob after firebase purged their AdMob APIs a couple years ago).

We have run into this fluid banner android thing as well and your repo was just mentioned here invertase/react-native-google-mobile-ads#130 - Honestly I had looked around at all react-native google ads repos I thought but did not see this one!

That said, I have two questions if you have the time to answer?

1- in your experience, is it really true that any event at all from the android underlying SDK for a banner ad means it is a fluid ad? That seems...risky to just assume it but you all have the experience clearly

2- would you be interested in joining forces with us so we have one repo with more maintainers? As a maintainer of a lot of repos myself, I always enjoy it more when there are more maintainers to spread the workload. Additionally, we have built-in UMP / consent form handling, support for hooks, and in my work with Invertase (the supporting company) I handle most of the day-to-day administration (like dependencies, CI, release automation, example app management, issue triage etc), but we have 4 active developers and a few active testers at the moment so it's a good crew. Here's a similar pitch I made to the only other native ads implementation I'm aware of in case you're interested - ammarahm-ed/react-native-admob-native-ads#274 - either way cheers! :-)

I don't believe this PR actually solves this problem. I created a bare native app and added the banner, and it is cutoff.
