If .probe p(Q1) is found, flag power is true, then do additional power calculations:
Define a reference voltage of an n-terminal device as Vref = (V(1) + V(2) +...+ V(n)) / n with terminal (node) voltages V(n).
Calculate power PQ1 = (v(1) - Vref) * i1 + (V(2) - Vref) * i2 + ... + (V(n) - Vref) * in) with terminal currents in.

probe_int_ is used to trigger supressing the vectors when saving the results. Internal vectors thus are
not saved. */
