"""
Find the coordinates of the pixel with the maximum value in a GeoTIFF file.
Args:
geotiff_file (str): Path to the GeoTIFF file.
band_dix (int, optional): The band index (default is 1).
dst_crs (str, optional): The destination CRS in EPSG format (e.g., "EPSG:4326").
If None, returns the original x, y coordinates.
Returns:
tuple: x, y coordinates of the pixel with the maximum value, and the maximum value.
