Interactive image doesn't receive mousemove events

[falkoschindler]

Description

As reported on r/nicegui, it is currently not possible to receive mousemove events for ui.interactive_image if the cross hair is active.

This seems to be caused by the way registered events are collected. The events needed to update the crosshair overwrite the mousemove events requested by the user:

nicegui/nicegui/elements/interactive_image.js

	const allEvents = {};
	for (const type of this.events) {
	allEvents[type] = (event) => this.onMouseEvent(type, event);
	}
	if (this.cross) {
	allEvents["mouseenter"] = () => (this.cssDisplay = "block");
	allEvents["mouseleave"] = () => (this.cssDisplay = "none");
	allEvents["mousemove"] = (event) => this.updateCrossHair(event);
	}
	allEvents["load"] = (event) => this.onImageLoaded(event);
	return allEvents;
