'NoneType' object has no attribute 'groups'

[JulioContrerasH]

This issue occurs when attempting to extract coordinates using the regular expression in main.py:

coords = chunk["stac:centroid"].apply(lambda x: point_pattern.match(x).groups())

Steps to Reproduce:

1. Check the stac:centroid column for coordinates near zero.
2. Try applying the point_pattern.match(x) to such rows.

Expected Behavior:
The code should handle invalid or near-zero coordinates gracefully and avoid the 'NoneType' error.

Suggested Fix:
Add a check for None before calling .groups() to handle invalid matches properly.
