grid_rect

Creates hexagon polygons covering a rectangular geographic region.
For H3 grids, all cells that overlap the bounding box are included
(not just cells whose center falls inside), ensuring full spatial coverage.

Provides functions to build and use hexagonal discrete global grids
using the 'Snyder' 'ISEA' projection ('Snyder' 1992
<doi:10.3138/27H7-8K88-4882-1752>) and the 'H3' hierarchical hexagonal system
('Uber' Technologies). Implements the 'ISEA' discrete global grid system
('Sahr', 'White' and 'Kimerling' 2003 <doi:10.1559/152304003100011090>).
Includes a fast 'C++' core for 'ISEA' projection and aperture quantization,
an included 'H3' v4.4.1 C library for native 'H3' grid operations, and
'sf'/'terra'-compatible R wrappers for grid generation and coordinate assignment.
Output is compatible with 'dggridR' for interoperability.
