- 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.

- Move direct handling of data loggers into ExternalSensors

- remove commit log comments
- fix code formatting

allow downwards sweeps

- replace TestData for PorstPlot with data of last successful sweep
- error handling class for datalogger almemo 710 and almemo 2490
- loop for multiple request of sensor data removed because included in erro handling of class for data logger
- update of test data
update play files for single work with data logger

- implementation of data logger into test stand software as alternative to model 710
- configuration vy test_stand_parameter.json

- new function ins post plot for plotting analysis parameter
- PlotData from Test of modules added

env_cond_sensors key in jsonfile update to ext for requesting information from external sensors for measurement instrument chamber

- subplot 5 modified that heater activity, external sensors and sensors of climate - chamber from instrument chamber can be display
- request of instrument chambers added
- configurable option in json file for selecting parameter in subplot5

Debug Complete

- 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

analysis functions module for correlation and regression

analysis functions for postplot added

-> actually used for postplot analysis (correlation/regression)
