Build fails on Electron 42+/V8 13 (nan + C++20)

Problem

Rebuilding @grandchef/node-printer@0.8.0 against Electron 42+ (tested with Electron 43.3.0, darwin arm64) fails.

1. Outdated nan vs V8 13 APIs

Compilation fails inside nan headers with errors such as:

• v8::External::Value / New now require ExternalPointerTypeTag
• GetAlignedPointerFromInternalField / SetAlignedPointerInInternalField signature changes
• v8::AccessControl removed in newer V8

These are covered by nan@2.28.0 (nodejs/nan#1015, changelog 2.28.0).

Current dependency: "nan": "^2.19.0" often resolves below 2.28.0.

2. C++17 is no longer enough

Even after fixing nan, Electron/Node headers emit:

#error "C++20 or later required."

binding.gyp still sets -std=c++17 / -std:c++17 for macOS / Linux / Windows.

Environment

• Electron 43.3.0
• macOS darwin arm64
• Rebuild via @electron/rebuild / electron-builder install-app-deps

Proposed fix

1. Pin/bump nan to 2.28.0
2. Raise binding.gyp language standard to C++20 on win/mac/linux

I can open a PR with that patch.
