feat: introduce Node.js handler

[yusukebe]

Fixes #25

This PR introduces a new handler for Node.js - hono-remix-adapter/node. You can use it to run your app on Node.js:

// main.ts
import { serve } from '@hono/node-server'
import { serveStatic } from '@hono/node-server/serve-static'
import handle from 'hono-remix-adapter/node'
import * as build from './build/server'
import { getLoadContext } from './load-context'
import server from './server'

server.use(
  serveStatic({
    root: './build/client',
  })
)

const handler = handle(build, server, { getLoadContext })

serve({ fetch: handler.fetch, port: 3010 })

To run the server, using tsx is easy way:

tsx main.ts

Or you can compile to a pure JavaScript file with esbuild with the command below:

esbuild main.ts --bundle --outfile=main.mjs --platform=node --target=node16.8 --format=esm --banner:js='import { createRequire as topLevelCreateRequire } from "module"; const require = topLevelCreateRequire(import.meta.url);'
