TypeScript EventHandlers do not support all properties in payload

[Falke-Design]

In the event payload there is always the source and the possibility to add custom properties. Is it possible to extend types and make a base event type with source and custom properties?

TS:

leaflet-geoman/leaflet-geoman.d.ts

Lines 1437 to 1440 in 1fdc918

	export type GlobalRotateModeToggledEventHandler = (e: {
	enabled: boolean;
	map: L.Map;
	}) => void;

JS where the payload and the custom payload are merged:

leaflet-geoman/src/js/Mixins/Events.js

Lines 615 to 618 in 1fdc918

	__fire(fireLayer, type, payload, source, customPayload = {}) {
	payload = merge(payload, customPayload, { source });
	L.PM.Utils._fireEvent(fireLayer, type, payload);
	},

@ryan-morris maybe you have time to check this?
