When performing an IV ramp using an SMU, it's important to measure both current and voltage in every ramp step. The SMU compliance limits can modify the actual voltage applied, differing from the set value. This requires following changes:
adding method measure_iv() to all instruments of base class SourceMeterUnit
use measure_iv() in all measurement instead of read_current()
adding columns v_smu[V] and v_smu2[V] to the output format
adding keys smu_voltage and smu2_voltage to RPC state method
