free
Frees the Wasm memory allocated for the GEOS geometry object.
GeometryRef objects are automatically freed when they are out of scope.
This mechanism is provided by the FinalizationRegistry
that binds the lifetime of the Wasm resources to the lifetime of the JS objects.
This method exists as a backup for those who find FinalizationRegistry
unreliable and want a way to free the memory manually.
Use with caution, as when the object is manually freed, the underlying Wasm resource becomes invalid and cannot be used anymore.
