// Usage:
// - Go to https://glaciermodding.org/rpkg/ and click "Download latest CLI"
// - Extract contents of downloaded zip file to packaging/add_itemsize/
// - From packaging/add_itemsize/ directory, run: node add_itemsize.js <path to Runtime> <Game Version (H1 / H2 / H3 / Scpc)>
// - E.g. node add_itemsize.js "C:\Program Files\Epic Games\HITMAN3\Runtime" H3
// - either H2 or H3 Runtime path seem to work for Scpc Game Version
