Updated requirements and fixed VTK export

1.2.3

Removed unnecessary packages & bugfix in vtk export

Cleanup and LIM improvements

• Improved line intercept method
• Update to Python 3.12
• ARAMIS export and Simulations moved to its own repository

Bugfix Williams stress field

• Fixed bug in Williams stress field formula (no influence on fracture analysis)
• Fixed missing import statement
• Added script for plotting CJP-stress and displacement field
• Cleanup of structure_elements and dic_utils

Crack tip correction & Line intercept method

We implemented the following new features:

• Another crack detection algorithm based on a line intercept method (LIM)
• Fine-tuning of the crack tip position with a correction formula based on Williams coefficients
• JSON-export of fracture analysis data
• Bugfixes in DIC module

Bugfix in automatic setting of integral properties

• Bugfix in atuomatic setting of integral properties used in crack analysis pipeline
• Bugfix in multiprocessing of crack analysis pipeline

Colormaps, Improved Crack Detection & Bugfixes

• Scientific colormaps / possibility to define colormaps globally
• Errors in fracture analysis' fitting methods are treated by writing NaN's into output textfiles
• Crack detection pipeline: Fixed issue with sorting of nodemaps
• Warning when NaN's are in input data
• New parameter detection_boundary in CrackDetectionPipeline to specify a maximal window for crack detection
• Plots of crack detection results are created automatically with the pipeline
• VTK export fixed
• Removed stress field fitting methods in optimization.py (not needed currently)

Hotfix PyVista

• Downgraded to PyVista 0.37.0
• Deleted unnecessary output files
• Improved gitignore to avoid unintended git --add of output files

Nodemap to vtk converter

• Nodemap to vtk converter added to InputData class
• Added connection files to test data

Hotfix PyTorch dependency >=1.13.1

Updated requirements to ">=" version number
Updated PyTorch dependency to >= 1.13.1

Hotfix von Mises strain

Fixed typo in data_processing.InputData.calc_eps_vm which resulted in wrong von Mises equivalent strain.
