add support for other GeoJson types (LineString, MultiLineString)

From: Screen Shot 2023-01-24 at 10.40.45 AM

Note that we only accept GeoJSONs of type "FeatureCollection" or "Feature" with geometries of type "Polygon" or "MultiPolygon".

I see a few references to LineString and MultiLineString here but I'm uncertain if they are actually support or if the docs are old?

Here is a CodePen that should work if this feature was supported.

首先检查 src/lib/geojson_utils.js，并复现链接的 CodePen 示例，以跟踪 Feature 和 FeatureCollection 几何图形的处理方式。确定现有对 LineString 和 MultiLineString 的支持，然后验证这两种 GeoJSON 类型是否能与 Polygon 和 MultiPolygon 输入一起正确渲染。
