feat: Simple Distributed Mode

[KnorpelSenf]

Running multiple instances of a bot is currently possible by composing low-level objects such as sources and sinks, and connecting them manually via a runner.

It would be cool to just do runDistributed(bot) and get all of that for free.

• Should start as many threads as there are CPUs - 1 (configurable)
• Should distribute entire update batches so that parsing and reparsing JSON responses can be avoided (rather pass raw byte buffers, and parse on threads)
• Should optionally provide a way to order updates, such as with sequentialize. It may be necessary to perform parsing in the central node. In that case, repeated parsing cannot necessarily be avoided that easily.

Would this be a good API?

// bot.ts
const bot = new Bot("token");
bot.use(sequentialize((ctx) => ctx.chat?.id.toString()));
runDistributed(bot, "./worker.ts");

// worker.ts
const worker = new BotWorker();
worker.on("message", (ctx) => ctx.reply("brrr"));
