Exception when starting device monitor

[THuckemann]

When I try to run the device monitor as described in the readme I get the following exception:

runcell(7, 'C:/Users/Huckemann/Documents/Python/Projects/qumada/src/examples/device_object_example.py')

Using ipython (Spyder) and the commit 16b7de3. Had to manually install some of the required packages, not all where listed in the setup file with a required version.

For reference, PR #164

@THuckemann I added a sentence about the dependencies to the README

Issue still persists on some PCs, even in fresh conda environment.

We need the error of the called process for better debugging.

832bfee on feature/dash_device_monitor shoudl fix that.

I also no longer require a spcific qt backend but this shouldnt be a problem.

[THuckemann]

The improved error message is below. It seems to depend on the dxf file used, I was able to open a different one now.
I attached the one that causes the issue.

[shumpohl]

Thanks, I will debug.

The problem is that no gates are read from the dxf file. Maybe related to the default cropping region?

[shumpohl]

The coordinate range in v6 is not centerered. I will include an optional automatic centering step and more documentation.

[shumpohl]

At least this cause is now fixed in feature/dash_device_monitor

I added a step that identifies the ROI by the feature size, i.e. the distance of line defining points.
