v5.8.0

• Distribution: CocoaPods and Carthage support have been dropped. The SDK is now distributed
  exclusively through Swift Package Manager via tags on the public FeedMedia repo.
• Feature: New searchForAndSetActiveStation: method that searches for a matching station and
  sets it as active in a single API request, with optional audio preparation for faster playback.
• Feature: New FMStationSearchQuery class for building typed station search queries with
  MongoDB-style filters. Supports radio, first_play, and replay station types.
• Feature: New requestPlayWithStationSearches method with support for specifying audio
  formats and bitrate.
• Feature: Network throttling support via new useBackgroundNetworkServiceType property on
  FMAudioPlayer. When enabled, audio downloads are deprioritized when competing for bandwidth.
• Feature: New FMResourceMonitor that tracks free disk space and available memory, with
  low-disk and low-memory detection. Resource metrics are included in analytics events.
• Feature: FMStation now exposes a placementID property.
• Feature: New error codes FeedFMErrorCodeRequestTimeout, FeedFMErrorCodePlayerCouldNotSetStation,
  and FeedFMErrorCodePlayerPrepareTimeout.
• Fix: Fixed skip error handling.
• Fix: Fixed play method return value (now returns BOOL indicating success).
• Fix: Corrected the activeStation nullability annotation from nonnull to nullable. It
  returns nil before the player is initialized and whenever no station is active.
• Cleanup: Removed the unused FMAudioPlayerStationListAvailableNotification constant. The
  notification itself was removed in v4.0; only the orphaned symbol remained.
• Improvement: Better memory management for active download tasks using NSMapTable.
• Improvement: More sophisticated logic for detecting HTTP range request support.
• Improvement: Updated documentation for completion handler methods.
