vec_to_tiff

Writes the level-0 pixels of a <code>.vec</code> raster to a GeoTIFF file. The
TIFF inherits dtype, geotransform, EPSG, and nodata from the source.
Strip layout; the writer supports <code>"none"</code>, <code>"deflate"</code>, and <code>"lzw"</code>
compression. LZW also applies horizontal differencing (Predictor 2)
for integer pixel types, which dramatically improves compression on
smooth raster data and matches the layout most production GIS tools
produce by default. Tiled and BigTIFF output land in a follow-up.

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.
