delete_vtr

Marks the specified 0-based physical row indices as deleted by writing (or
updating) a tombstone side file (<code>&lt;path&gt;.del</code>). The original <code>.vtr</code> file is
never modified. The next call to <code>tbl()</code> on the same path will automatically
exclude the deleted rows.

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.
