Extract Large-Scale Statistics in Drive Mode with Fewer Tasks

Batches multiple geometry chunks into fewer ee_table_to_drive tasks, reducing overhead and leveraging Google Earth Engine's parallel processing.

`stat_fun`	[mandatory] (ee$Reducer) The Earth Engine reducer function.
`scale`	[mandatory] (numeric) The spatial resolution in meters for reduceRegions.
`folder`	[optional] (character) Name of the Google Drive folder where exports will be stored. Defaults to `".geelite_tmp_drive"`.
`user`	[optional] (character) GEE user profile name, if applicable.
