Add uziom generation script and update wet input documents

- Created a new Python script `uziom.py` for generating DXF drawings of grounding systems based on user input parameters.
- Added detailed documentation in `wet_input_15.docx` and `wet_input_3.docx` for the design of grounding systems, including calculations for resistance and resistivity measurements.
- Included placeholders for dynamic data insertion in the documents to facilitate project-specific customization.
