bind_images_batch()

void MayaFlux::Yantra::GpuResourceManager::bind_images_batch	(	const std::string &	key,
		const std::vector< ImageBind > &	images
	)

Bind every image in one Vulkan call.

Equivalent to calling bind_image_storage or bind_image_sampled once per entry (routed by spec.element_type), except every entry is submitted through a single vkUpdateDescriptorSets call. Also records each image in the pipeline unit's image_slots, same as the per-call methods.
