feat: Allow starbase to be published

[Ehesp]

Purpose

This PR allows starbasedb to be published to NPM and used in standalone apps. I've verified this works when locally linked.

Some docs need adding on how to do this, but the general flow is:

1. Install

npm i --save starbasedb

2. Setup (wrangler.toml)

[[durable_objects.bindings]]
name = "STARBASEDB"
class_name = "StarbaseDBDurableObject"

[[migrations]]
tag = "v1"
new_sqlite_classes = ["StarbaseDBDurableObject"]

3. Export

In your index.ts file:

export { StarbaseDBDurableObject } from 'starbasedb';

4. Use / import

import { StarbaseDB } from 'starbasedb';

...


const stubId = env.STARBASEDB.idFromName('TEST');
const stub = env.STARBASEDB.get(stubId);

const rpc = await stub.init()

const starbase = new StarbaseDB({
	dataSource: {
		rpc,
		source: 'internal',
	},
	config: {
		role: 'admin',
	},
});
