- featues a cancel button and clean exit when the measurement plot window is closed

- introduce multiple measurement sets in the dut_measuremets
- create one plot per measurement set for time traces
- analysis is showing all sets against temperature/humidity

All notions of VNA, magnitude and phase in prototype.py and the GUI have been
removed and generalised.
This is just refactoring, no functional change. However, the syntax of the
config file has been adapted.

- remove commit log comments
- fix code formatting

- in ext_sensor_channels.json key names for mapping sensor channels to measured values renamed
- comments in TeststandGUI.bat and new path settings
- edit names for import jsofile ext_sensor_channels.json in climate-lab-gui.py
- edit names for reference to keys in ext_sensor_channels.json
- edit import routine in prototype.py for import of external sensor data

### long term run with step from 25 to 30 °C sucessful ###

bug fixes import teststand json file
time unit configuration switched from ext_sensor_param.json to test_stand.json
host names of meas_equipment devices replaced by IP adress -> reason: otherwise no connection possible
batch file for program start included -> Path in batch must be corrected to location of program

------------------
after test with long term run version should be tagged

in parameter list of method prototype.Measurements logger ip added to parameter list

modify module for measurement plot for external sensors
add module for post
modifiy prototype for external sensors and error handling of communcation errors of VNA
add regresson to post plot with basich control elements
