Drop legacy import/export syntax

[merlinnot]

This package uses legacy import/export syntax, the proposal was withdrawn and this syntax should not be used:

firebase-functions-test/src/index.ts

Line 29 in a25faf5

export = (firebaseConfig?: AppOptions, pathToServiceAccountKey?: string) => {

firebase-functions-test/spec/providers/https.spec.ts

Line 3 in c77aa92

import fft = require('../../src/index');

We could either use default export, or preferably a named one, but it would be a breaking change, so I won't make a PR before we align on this.

Absolutely agreed, I'll probably snap this twig on the next major release.

[merlinnot]

@abeisgoat Is this package still maintained? Is it worth to start making PRs?

[laurenzlong]

Hey @merlinnot sorry for the long silence! We've definitely dropped the ball on our side, and will start showing this repo some more love. Yes you're very welcome to start making PRs, and we'd be happy to review.
