Update to 0.082
    
    - New upstream release 0.082
      - The relative() method no longer uses File::Spec's buggy rel2abs method;
        the new Path::Tiny algorithm should be comparable and passes File::Spec
        rel2abs test cases, except that it correctly accounts for symlinks
      - Added 'edit' and 'edit_lines' plus _utf8 and _raw variants; this is
        similar to perl's -i flag (though without backups)
      - Fixed lines_utf8() with chomping for repeated empty lines
      - Fixed lines_utf8+chomp and relative() bugs on Windows
      - Documented that subclassing is not supported
