[REQUIRED] Step 1: Describe your environment

• Xcode version: Version 12.0 (12A7209)
• Firebase SDK version: 6.34-spm-beta branch
• Firebase Component: Admob (Auth, Core, Database, Firestore, Messaging, Storage, etc)
• Component version: _____
• Installation method: Swift Package Manager (select one)

[REQUIRED] Step 2: Describe the problem

I tried to use SPM instead of Carthage for installing Firebase iOS SDK.
I followed https://github.com/firebase/firebase-ios-sdk/blob/master/SwiftPackageManager.md#in-xcode but there is no Admob package. Can I install Admob package via SPM?

Steps to reproduce:

follow https://github.com/firebase/firebase-ios-sdk/blob/master/SwiftPackageManager.md#in-xcode

Relevant Code:

(When I use Carthage, I wrote in Cartfile like below)

binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseAdMobBinary.json"
binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseAnalyticsBinary.json"
binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseRemoteConfigBinary.json"
