feat: remove override #41
Description
Hello,
The local override feature is very useful for testing. However, once an override is set, there is no way to remove it and restore the flag's original behavior without re-initializing the client.
This complicates test setups where we need to check both the overridden and default states of a flag.
Could you please consider adding the RemoveGateOverride method? This would significantly improve the testing workflow.
