Overhaul and update project

[basicdays]

• Breaking Change: Dropping support for Node 11 and below.
• Breaking Change: Dropping support for Flow.
• Bug Fix: Resolves End handlers not being removed after next resolve #5. Event handlers are cleaned up after each iteration, fixing some memory leak issues.
• Bug Fix: Resolves Emitted code uses regeneratorRuntime #7. Code no longer depends on babel runtimes or regenerator.
• Bug Fix: Handles stream not buffering due to starving the event loop.
• Feature: Resolves Add .throw and .return interface methods to StreamToAsyncIterator #1. Now handles .throw and .return hooks on the async iterator.
• Feature: Properly closes stream when finished.
• Feature: Added support for TypeScript.
• Feature: Support for Node.js versions 12, 14, and 16.
• Chore: General overhaul of project setup (should not impact what is published).

Not sure if you are aware, but in Node 12+ the Readable stream implements asyncIterator already:

#!/usr/bin/env node
"use strict";
const { Readable } = require("stream");

(async function () {
    const readStream = Readable.from([1, 2, 3]);
    for await (const chunk of readStream) {
        console.dir({ chunk });
    }
})();

@LinusU It was more an attempt to get this to wrap around a db driver module that used an instance of Readable that they somehow made themselves. No luck unfortunately, but did all this work, figured I'd just as well publish it anyways. I should probably move the node support to legacy though so that it might be useful on very legacy projects.
