[dlenroc]

Changes

• Set appium@2.3.0 as the minimum supported version to get ESM support.
• Updated to latest version of Roku SDK for internal use.
  • Fixes GH-67 by matching the current active behavior with roku automation solution.
  • Fixes GH-66 by showing additional information in errors.
• Updated getPageSource to return the page source directly, without parsing using roku-dom.
• Fixed clearing/setting state and passing launch arguments in cases where fullReset capability is passed or the application is not yet installed.
• Added an AbortController that closes roku clients to ensure that no commands will be sent after the session deletion.
• Switched to Appium's built-in logger to make it easier to see which session logs are associated with.
• Set libxmljs2 to 0.32.0 version to preserve the same OS/Node.js/CPU-s support as before.
• Added support for Windows OS.
