Inferred types of default AuthPipes are incompatible with `AuthPipe` under TypeScript strict mode

[wSedlacek]

Version info

**Angular: 9.1.9

**Firebase: 7.14.6

**AngularFire: 6.0.0

How to reproduce these conditions

app-routing.module.ts

import {
  AuthPipeGenerator,
  canActivate,
  redirectUnauthorizedTo,
} from '@angular/fire/auth-guard';

const redirectUnauthorizedToLogin: AuthPipeGenerator = () => redirectUnauthorizedTo(['login']);

With Strict mode enabled.
tsconfig.json

{
  ...
  "compilerOptions": {
    ...
    "strict": true,
  },
}

Debug output

Type 'UnaryFunction<Observable<User>, Observable<true | any[]>>' is not assignable to type 'AuthPipe'.ts(2322)

Expected behavior

redirectUnauthorizedTo should return the shape of AuthPipe even while under Strict mode.

Actual behavior

redirectUnauthorizedTo and a few other helper pipes have the typing of UnaryFunction<Observable<User>, Observable<true | any[]>>

Type cast the result of your auth factories with as as a temporary work around.

@koraysels looks like my patch got merged. If you are still having issues after that lands you may want to see if there's another issue that more closely resembles the circlet dependencies you described or create a new issue.
