Subject: [PATCH] Add isAbsolutePath utility and update path handling

Introduced isAbsolutePath function in file.js to robustly check for absolute paths. Updated msoffice.js to use this utility for file path resolution in Excel.open, improving cross-platform compatibility and reliability. Version numbers incremented in both files.
