estimate-area returns with `too many values to unpack` error

从 mapbox_tilesets/scripts/cli.py 中的 estimate_area 入口点和 mapbox_tilesets/utils.py 中的 calculate_tiles_area 开始，然后使用报告的 NDGeoJSON Point 几何重现该命令。跟踪几何如何到达 supermercado 的 burn 函数，并验证 estimate-area 能够完成并针对所提供的输入返回面积估算值。

I'm trying to get an estimate of the cost for the MTS publish process.

With the CLI and the estimate-area command, the program exists with an error.

*****/dist$ tilesets estimate-area -p 10m --no-validation wpt.geojson.l

the provided file is NDGeojson of about 2500 lines with a pretty long object, but with a very simple geometry part. eg:
