This commit introduces a new 'borg export' command that allows users to convert proprietary archives (.stim, .trix, .dat) into widely-supported formats.
Key features include:
- Export to directory, zip, and tar.gz formats.
- File filtering using `--include` and `--exclude` glob patterns.
- Password-based encryption for zip file output using the `--password` flag.
The command handles both standard and encrypted input archives, making it easier to share data with users who do not have Borg installed.
