5.4.4

Fixed

• Fixed memory leak when stream connections are terminated by updating LDSwiftEventSource dependency to 1.3.0.
• The SDK would not allow additional fields on delete flag stream events. This has been updated to allow additional fields for improved future compatibility.
• Improved internal Throttler implementation to reduce concurrency concerns.
• Removed unneeded Cartfile defining LDSwiftEventSource dependency, which when bundled could lead to warning messages that LDSwiftEventSource definitions are implemented in multiple frameworks.
