aider: Moved the `ExtendedEvent` type and interface to `simplelog.go`.

# Aider chat conversation:

USER: the extendedevent type and interface should be in simplelog.go not the relp_handler.go because it's general to the simplelog package and not specific to the relp extendedhandler.

ASSISTANT: To move the `ExtendedEvent` type and interface to `simplelog.go`, we need to:

1. Remove the `ExtendedEvent` type and interface from `event.go`.
2. Add the `ExtendedEvent` type and interface to `simplelog.go`.

Here are the *SEARCH/REPLACE* blocks:

event.go
```go

type ExtendedEvent interface {
	GetID() uuid.UUID
	GetTimestamp() time.Time
	GetLevel() string
	GetMessage() string
	GetData() json.RawMessage
	GetFile() string
	GetLine() int
}

type extendedEvent struct {
	Event
	File string `json:"file"`
	Line int    `json:"line"`
}

func (e extendedEvent) GetID() uuid.UUID {
	return e.ID
}

func (e extendedEvent) GetTimestamp() time.Time {
	return e.Timestamp
}

func (e extendedEvent) GetLevel() string {

func (e extendedEvent) GetMessage() string {

func (e extendedEvent) GetData() json.RawMessage {
