Update for Google-Mobile-Ads-SDK v11

[dev-arekusandoru]

Hello, there is not one specific issue that I am addressing, but I would like to request that you update the entire package to work with the latest version of the Google-Mobile-Ads-SDK.

I have been trying to figure out a way to get this package working in my latest Expo project (SKD 51), and has been quite impossible so far. Here are some things I have noticed that have made the process more confusing and difficult.

1. The documentation appears to be outdated, suggesting the use of the Google-Mobile-Ads-SDK v9. The documentation is also very scarce. Please update this, and it would also be helpful to indicate where in the podfile the pod line needs to be added.
2. Update the package version on npm. There have been fixes pushed to the master branch related to issue #359 , but they are only accessible by installing with the command npm i ammarahm-ed/react-native-admob-native-ads,
3. With the most recent version of the code, the build error is fixed but after building and installing a development build on iOS, the build will crash on launch, with no errors given.
4. Because the code and documentation are relying on an outdated version of the Google-Mobile-Ads-SDK, there is conflict when using this package in tandem with the react-native-google-mobile-ads package.

I hope this issue is addressed quickly, as I would love to use this package in my project! Please let me know if you would like any further clarification of any of the points I have listed above.
