Wildfire Burn Severity Analysis - v1.1.0

Overview

This update introduces pluviometry/precipitation data analysis using CHRIPS v2 collection (Climate Hazards Group InfraRed Precipitation with Station Data).
Users can now generate daily precipitation levels in the report for the selected pre/post fire dates, enabling better environmental assessment of wildfire conditions. Precipitation data is available in both tabular (dataframe) and graphical (Altair chart) formats, with options for sorting, full-screen viewing and data export in various formats (csv, png/svg).
