EventBufferEvent::free — Free a buffer event

### Description

public EventBufferEvent::free(): void

Free resources allocated by buffer event.

Usually there is no need to call this method, since normally it is done within internal object destructors. However, sometimes we have a long-time script allocating lots of instances, or a script with a heavy memory usage, where we need to free resources as soon as possible. In such cases EventBufferEvent::free() may be used to protect the script against running up to the `memory_limit`.

### Parameters
