apply_direct()

void apply_direct	(	const TTruncAcc &	acc,
		TMatrix< value_t > *	dest = nullptr,
		const bool	update_dest = false
	)

compute and apply local direct updates;

• use dest as hint for destination type, e.g. to choose format of accumulator
• directly update dest if update_dest == true (accumulator is zero afterwards)
