dggrid_is_compatible

Checks whether a 'dggridR' grid object is compatible with hexify functions.
Returns TRUE if compatible, or throws an error describing incompatibilities.

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