/// Represents a parser for MTA GTFS-realtime data feeds for multiple subway lines.
/// </summary>
/// <remarks>
/// This class fetches and parses GTFS-realtime feed data from the MTA API for specific subway lines:
/// Orange, Blue, Yellow, and Red/Green.  
/// It stores the feed URLs internally and provides asynchronous methods to fetch and process the data.  
/// Parsing focuses on FeedEntities, such as TripUpdates, which can then be used for further processing or display.
