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.
