[kylebarron]

Improved shapefile typing

• Improved Batch typing
• Improved zip-batch-iterators, taking inspiration from https://github.com/visgl/loaders.gl/pull/2073
• Coalesce all Shapefile types into types.ts
• Rename RowArrayTableBatch to ArrayRowTableBatch and RowObjectTableBatch to ObjectRowTableBatch to be aligned with ArrayRowTable and ObjectRowTable
• Improved Shapefile return objects
  • extends GeoJSONRowTableBatch for the batched parser and GeoJSONRowTable for the sync parser
• Improved Shapefile typing
  • Removes several anys

Would close #2073 and #2072.
