The smoke test can be performed on a single or multiple BTS7040

• CURRENT_MEASURE_INTERVAL_MS: wait time between each set of readings

• IS_FRONT_POWER_DISTRO: set to true for front and false for rear power distribution

• s_test_channels: set of channels to be tested, contains the indices of the BTS7040 in front/rear HW config
