Enhancement: compatibility with Electron 21 will require copying all memory Buffers, will have performance cost

Possible bug

Is this a possible bug in a feature of sharp, unrelated to installation?

• Running npm install sharp completes without error.
• Running node -e "require('sharp')" completes without error.

Are you using the latest version of sharp?

• I am using the latest version of sharp as reported by npm view sharp dist-tags.latest.

What is the output of running npx envinfo --binaries --system --npmPackages=sharp --npmGlobalPackages=sharp?

What are the steps to reproduce?

Run sharp with electron 21

What is the expected behaviour?

Sharp should be compatible

Please provide a minimal, standalone code sample, without other dependencies, that demonstrates this problem

{
  "dependencies": {
    "electron": "^21.0.0-beta.8",
    "sharp": "^0.31.0"
  },
  "scripts": {
    "test": "electron main.js"
  }
}

const sharp = require('sharp')

const semiTransparentRedPng =  sharp({
  create: {
    width: 48,
    height: 48,
    channels: 4,
    background: { r: 255, g: 0, b: 0, alpha: 0.5 }
  }
})
  .png()
  .toBuffer();

It is important to run the script through electron, and it has to be v21+

Please provide sample image(s) that help explain this problem

This is because of a change electron have made, which breaks compatability for some native modules https://www.electronjs.org/blog/v8-memory-cage

Electron 21 was released on the 27th September, and I have opened an issue to complain about their breakage of the guaranteed stable node-api that electron are doing here. https://github.com/electron/electron/issues/35801

[826378:0924/183534.268000:ERROR:node_bindings.cc(146)] Fatal error in V8: v8_ArrayBuffer_NewBackingStore When the V8 Sandbox is enabled, ArrayBuffer backing stores must be allocated inside the sandbox address space. Please use an appropriate ArrayBuffer::Allocator to allocate these buffers.

v0.31.3 now available with a workaround for the V8 memory cage.

Please remember you’ll need a future version of Electron that provides the patched version of Node.js to take advantage of this.

Commit https://github.com/lovell/sharp/commit/584807b4f5e1b831785c79eef5367f737589f29b adds this and it will be part of v0.31.3.
