Lgvisium 100/extract depth value error handling

[lhaibach]

Changes done:

• In the extract_depth function, the ValueError handling has been incorporated, and the matched pattern are now more specific to groundwater depth. This change reduced the number of ValueErrors encountered during float conversion, which previously caused the process to exit the loop prematurely. However, this refinement has led to an increase in false positives.

• To reduce these false positives, the logic for finding groundwater information has been changed. Groundwater search is now directly tied to the material description bounding box, meaning groundwater data is only search for in areas associated with material descriptions. This adjustment reduces unnecessary searches on pages without material descriptions and ensures groundwater extraction is more contextually related to material description areas. Since groundwater details can sometimes appear at the end of a page or farther from the material description, the search around the bounding box is not overly strict.

• To further reduce false postitives the logic for finding lines near keys was changed (impacting coordinate, elevation, and depth extraction). Instead of searching in a rectangle ( including entries diagonal to the key), the updated code now searches along the x and y axes. This adjustment improves the F1 score for groundwater extraction while slightly worsening performance for elevation extraction (data/geoquat/validation/ A11486.pdf).
