Correct setting of voltage limits when forcing PPMU current (#142)
* Correct the setting of voltage limit low for digital. * Add auto tests. * Add more tests. * Add new dependency. * Referece A as a dependency. * Add more auto tests. * Adjust implementation and auto tests. * Update summary documentation for ForceCurrentMeasureVoltage and ForceDcCurrent methods, and add all changes for these method to the CHANGELOG.md --------- Co-authored-by: mattjet27 <[email protected]>
