One needs heavy libraries and a Google account to run locally

As was mentioned in #88, the emulators for Firebase are not very light on minimalistic in any sense of the word.

In addition to that, I was forced to create a Google account to test Simlin locally.

Is there any way that we can quickly implement an alternative backend? I would love to just use an SQLite database to store everything, including user data. I believe Passport allows for that. If it makes it easier in the beginning we might say that if you are running non-Firebase version, you can only login with email/password?

Thoughts?

seems reasonable - the hosting costs with firebase + firestore and google app engine are < $1 USD per month, which is the main reason I'm using them. I don't immediately want to switch app.simlin.com off of them without still supporting login-with-google/apple/etc, but happy to make it easier to run locally or elsewhere. ideally its some config or compatability API and not a deeply invasive change
