[bug] RangeError [ERR_FS_FILE_TOO_LARGE] when buffer set false.

[raoooool]

Describe the bug

Node.js version: v16.20.1

OS version: macOS 13.5.1

Description: the app crashes when attempting to read a file larger than 2GB.. setting config.buffer false.

Actual behavior

a file larger than 2GB located in the /public directory can cause the entire app to crash when attempting to read it.

Expected behavior

reading it normally.

Code to reproduce

const Koa = require("koa");
const path = require("path");
const staticCache = require("koa-static-cache");
const app = new Koa();

app.use(
  staticCache(path.join(__dirname, "public"), {
    buffer: false,
    dynamic: true,
    preload: false,
  })
);

app.use(async (ctx) => {
  ctx.body = "Hello World";
});

app.listen(3000);
