Address error

When going to reference local images in the .js file, the path should be introduced in the form of require(), modified as follows

billboard: {
        image: require("../img/boshi.png"),
        pixelOffset: new Cesium.Cartesian2(-120, 0),
        // eyeOffset: new Cesium.Cartesian3(0.0, 0.0, 0.0),
        horizontalOrigin: Cesium.HorizontalOrigin.LEFT,
        verticalOrigin: Cesium.VerticalOrigin.CENTER,
        // scale: 0.25,
        distanceDisplayCondition: new Cesium.DistanceDisplayCondition(100, 20000)
