forced require of non-existant buffer

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 6.8.0
• Cross-platform modules: 6.5.15
• Android Runtime: 6.5.3
• iOS Runtime: 6.5.2

Describe the bug
After updating the node_modules in my project including js-base64, starting the app resulted in an exception on trying to require the module buffer, which was never anywhere explicitly required.

According to the author (https://github.com/dankogai/js-base64/issues/126#issuecomment-674838031) the new version does check for existence of the Buffer object to maybe use it if available.

Expected behavior

Either do not add the require('buffer') or add buffer to the dependencies if not already there.

まず、記載された NativeScript のバージョンでアプリの起動を再現し、js-base64 から利用できない buffer モジュールまでの依存関係の経路を調査します。CLI の依存関係の宣言と起動処理を確認します。依存関係が利用可能になるか、require が導入されないことによって、アプリが利用できない require を試みなくなれば完了です。
