Re-enable ios constructors

[walkingbrad]

#349 commented out these constructors due to compilation issues. I think things are compiling fine now, for whatever reason, so I'm just uncommenting them back. Looks like there's just some build-time confusion about FirebaseApp types that a force-cast alleviates. Thanks @Daeda88!

Note: fun useFunctionsEmulator(origin: String) has been removed as it is no longer present in the latest Firebase version that this repo is now pointing to (it used to be deprecated).

Welp compilation issues do still exist. I'll keep investigating.

Error:

Type mismatch: inferred type is cocoapods.FirebaseCore.FIRApp but objcnames.classes.FIRApp was expected

Looks related to https://youtrack.jetbrains.com/issue/KT-56468

Its essentially a type alias, so you should be able to just cast. You'll get a warning that casting cannot succeed because the project cannot properly resolve the objcnames.classes package, but Ive tested on my own fork and there it works just fine

Looks to be working in my local setup as well! Thanks @Daeda88, I probably never would have tried this.

I am successfully publishing this lib to mavenLocal and running my iOS app that depends on a few of these iOS constructor APIs to load a dynamic FirebaseApp at runtime

I've tested these at runtime, and all the others should work too since the logic I introduced is the same:

• cloud functions
• firestore
• auth

Great stuff, thanks both!
