I set this up in my private repo fork months ago and do remember needing to update cocoapods and potentially bumping into one or two other minor changes I had to make, so this will need some testing and possibly adjustment to the Readme.
Why
Currently the Firestore iOS SDK depends on some 500k lines of mostly C++, which when compiling as part of your Xcode build takes a long time - even more so in CI environments.
This PR alters the source for the ios FirebaseFirestore pod to instead use the pre-compiled .xcframework binaries provided by https://github.com/invertase/firestore-ios-sdk-frameworks
