zippathlib 0.4.0

• Added warning when writing to an existing file in a ZIP archive. Writing to an existing file does not replace the contents of that file, but instead creates a duplicate entry. Calling ZipPath.write_text() or write_bytes() to an existing file will now raise a ZipPathDuplicateFileWarning.

• Added methods to ZipPath API to detect and purge duplicate entries:

  • scan_for_duplicates() returns a list of `(str, int) tuples, of all duplicated entries and their instance counts

  • purge_duplicates() removes duplicates by creating a copy of the current ZIP archive, copying only the latest version of each file, and then replacing the current ZIP archive with the purged copy

• Added CLI --check option, support for checking for large files or duplicates.

• Added CLI --purge option, support for purging duplicates, retaining only the latest.
