Complete _get_total_output() implementation in S4c driver

[coderabbitai]

Context

The _get_total_output() method in src/qcodes_contrib_drivers/drivers/QuTech/S4c.py currently has a placeholder implementation that only considers the range parameter when calculating the total output value.

What's Missing

The complete implementation should consider all relevant parameters:

• source_mode: Different scaling for voltage (V) vs. current (I) vs. voltage+resistance (V+R) modes
• R_out: Output resistance affects total output in V+R mode
• output_mode: Symmetric vs. single-ended affects output range
• x001_jumper: Should scale by 0.01 when installed

Dependencies

Before implementing this, the following must be completed first:

• IVVI rack summing module S2d/S2f drivers
• Interconnecting parameters between modules
