v4.4.0

Added

• RunAsLoop and RunAsSimulatedUpdateLoop operators, for running test instructions synchronously as a loop with a tick callback.
• Repeatedly operator, which turns a test responder into an optional responder that executes repeatedly.

Changed

• Include hint in state strings about being able to provide extra context to wait conditions
• Improve exception message handling by not truncating long messages (I don't remember why I did this originally)
• Add a bit of padding to the Unity operation status window

Fixed

• Fix some state strings on Windows, where Environment.NewLine is more than one character.
• Fix some cancellation issues with Unity 2021 (where cancellation might happen asynchronously later in the same frame)
