Add reusePort to listen SSLOptions

[MikkelSVDK]

This allows bunrest to function seamlessly in multithreaded workloads, leveraging the capability provided by Bun.spawn().

// spawn.ts
import { availableParallelism } from 'node:os'
import process from 'node:process'

const numCPUs = availableParallelism();

for (let i = 0; i < numCPUs; i++) {
  Bun.spawn(["bun", "index.ts"], {
    stdio: ["inherit", "inherit", "inherit"],
    env: { ...process.env },
  });
}

// index.ts
import server from 'bunrest'
const app = server()

app.get('/', (req, res) => {
  res.status(200).send('Hello, World!');
})

app.listen(3000, () => {
  console.log('App is listening on port 3000');
}, {
  reusePort: true
})
