mapbox将图层缩放到视口合适区域

1，通过@turf/bbox，获取minX, minY, maxX, maxY(经纬度) ，再转换成平面坐标，最后调用地图的实例方法fitScreenCoordinates

const geojson = this.map.getSource(id)._data
const bound = bbox(geojson)
const min = this.map.project([bound[0], bound[1]])
const max = this.map.project([bound[2], bound[3]])
this.map.fitScreenCoordinates(min, max, this.map.getBearing())
