Improving the basic accuracy of the uTracer6

[Bluesystems]

Here are the details of the changes I made to my utracer6 to improve low voltage at high current accuracy and to reduce failures of the MOSFET switch and driver transistors.

For more context see google group "https://groups.google.com/g/utracer" and threads "Improving the basic accuracy of the uTracer6" and "Utracer6 waveforms"

I invite comments and suggestions.
