Fix exiftool 13.50 download failure in build pipeline

[awoods]

Problem

Job 92389778222 is failing because the build cannot download exiftool version 13.50 from SourceForge. The download URL returns a 404 error.

Error Details

java.lang.RuntimeException: Failed to download file at https://sourceforge.net/projects/exiftool/files/Image-ExifTool-13.50.tar.gz/download. Status code: 404

The error occurs in the fits-tool-installer module during the Maven build when attempting to install exiftool as part of the build process.

Root Cause

The exiftool download link from SourceForge is broken or the file is no longer available at that URL. This is blocking the build pipeline from completing successfully.

Solution

1. Verify the current exiftool version available on SourceForge or use an alternative download source
2. Update the download URL to point to a valid source, such as:
   • GitHub releases: https://github.com/exiftool/exiftool/releases/download/13.50/Image-ExifTool-13.50.tar.gz
   • Direct official repository link
3. Consider upgrading to the latest stable version of exiftool if version 13.50 is no longer maintained
4. Update the tool installer configuration (likely in fits-tool-installer/pom.xml or installer code) with the corrected URL
