shortcut.vdf interaction

std::vector<u8> vdfFileContent = /* ... */;

steam::VDF vdf(vdfFileContent);

// Print game name of first entry
auto firstGameName = vdf["shortcuts"]["0"]["AppName"].string();
std::printf("%s", firstGameName.c_str());

// Hide first game from UI
vdf["shortcuts"]["0"]["IsHidden"] = true;

// Convert back to binary representation
auto binaryData = vdf.dump();

// Print vdf as formatted data
std::printf("%s", vdf.format().c_str());
