Cannot return `Buffer` when ETag middleware is used

[marvinruder]

When running the code

import { serve } from '@hono/node-server'
import { Hono } from 'hono'
import { etag } from 'hono/etag'

const app = new Hono()
app.use(etag())
app.get('/', (c) => c.body(Buffer.from('Hello Hono!')))
serve({ fetch: app.fetch })

and running curl localhost:3000, the server crashes:

node:internal/buffer:961
    super(bufferOrLength, byteOffset, length);
    ^

@marvinruder Thank you for rasing the issue. This seems to be a @hono/node-server bug.

Hey @usualoma, if you have a time, can you take a look?

I'll fix it, just wait a minute.

Works fine now in 1.12.1, thanks!
