GoogleMobileAdsFacebookMediation 3.2.0 conflict with GoogleMobileAdUnity 5.4.0

[REQUIRED] Step 1: Describe your environment

• Unity version: 2019.4.14f1
• Google Mobile Ads Unity plugin version: 5.4.0
• Platform: iOS
• Platform OS version: iOS 10
• Mediation ad networks used, and their versions: GoogleMobileAdsFacebookMediation 3.2.0, FBAudienceNetwork-6.2.1

[REQUIRED] Step 2: Describe the problem

iOS framework addition failed due to a CocoaPods installation failure. This will will likely result in an non-functional Xcode project.

After the failure, “pod repo update” was executed and succeeded. “pod install” was then attempted again, and still failed. This may be due to a broken CocoaPods installation. See: https://guides.cocoapods.org/using/troubleshooting.html for potential solutions.

pod install output:

Analyzing dependencies [!] CocoaPods could not find compatible versions for pod “GoogleAppMeasurement”: In snapshot (Podfile.lock): GoogleAppMeasurement (= 7.0.0, ~> 7.0)

In Podfile: Firebase/Core (= 7.5.0) was resolved to 7.5.0, which depends on FirebaseAnalytics (= 7.5.0) was resolved to 7.5.0, which depends on GoogleAppMeasurement (= 7.5.0)

GoogleMobileAdsMediationFacebook (= 6.2.1.0) was resolved to 6.2.1.0, which depends on
  Google-Mobile-Ads-SDK (>= 7.69.0) was resolved to 7.69.0, which depends on
    GoogleAppMeasurement (~> 7.0)

Hey folks, v6.0.0 is out now. This will enable mediation adapters that depend on GMA iOS SDK v8 or above and on GMA Android SDK v20 or above.
