Description: A minimal columnar query engine with lazy execution on
        datasets larger than RAM. Provides 'dplyr'-like verbs
        (filter(), select(), mutate(), group_by(), summarise(), joins,
        window functions) and common aggregations (n(), sum(), mean(),
        min(), max(), sd(), first(), last()) backed by a pure C11
        pull-based execution engine and a custom on-disk format
        ('.vtr'). Reads and writes 'GeoTIFF' (including tiled and
        'BigTIFF' layouts) and a tiled raster format ('.vec') with
        overview pyramids and time cubes for larger-than-RAM raster
        data. Streams vector operations (spatial transforms,
        point-in-polygon and nearest-feature joins including a
        two-sided grid-partitioned join, select-by-location, clip,
        erase, dissolve, rasterization, polygonization, and contouring)
        through 'sf', and runs raster operations (zonal statistics,
        focal windows, terrain derivatives, resample or reproject warp,
        polygon masking, map algebra, and mosaicking) in native C or
        over the tiled '.vec' format, one batch or tile at a time for
        data larger than RAM.
