 * Delete a tunnel route (CIDR Endpoint)

 * Deletes a private network route from an account. The CIDR in `ip_network_encoded` must be written in URL-encoded format. If no virtual_network_id is provided it will delete the route from the default vnet. If no tun_type is provided it will fetch the type from the tunnel_id or if that is missing it will assume Cloudflare Tunnel as default. If tunnel_id is provided it will delete the route from that tunnel, otherwise it will delete the route based on the vnet and tun_type.
