[colinodell]

Processors consist of a single function, so let's make it easier to run a single function as a processor.

Pull Request Overview

This PR introduces a ProcessorFunc type that allows using simple functions as event processors, making it easier to implement lightweight processing logic without requiring a full struct implementation of the Processor interface.

• Adds ProcessorFunc type that wraps a function with the processor signature
• Implements the Process method on ProcessorFunc to satisfy the Processor interface
• Includes comprehensive test coverage demonstrating usage with a notification filtering example

• The test only covers the success case. Consider adding a test case where the processor function returns an error to ensure error handling works correctly.

	notifications, err := event.ProcessorFunc(dropWithoutRecipients)(t.Context(), event.Event{}, []event.Notification{notificationWithRecipient, notificationWithoutRecipient})
