Scales the voltage, current, and power of the DataFrames
returned by :py:func:`singlediode` and :py:func:`sapm`.

Parameters
----------
data: DataFrame
    Must contain columns `'v_mp', 'v_oc', 'i_mp' ,'i_x', 'i_xx',
    'i_sc', 'p_mp'`.
voltage: numeric, default 1
    The amount by which to multiply the voltages.
current: numeric, default 1
    The amount by which to multiply the currents.

Returns
-------
scaled_data: DataFrame
    A scaled copy of the input data.
    `'p_mp'` is scaled by `voltage * current`.
