ScanZip Improvements - Limits Changes, Zero File Size Support, Encryption Updates

[ryanohoro]

Describe the change

Adds to ScanZip:

• Support for files with zero size (does not emit them)
• Configurable size limit on extracted files
• Configurable ability to collect metadata beyond the specific file count limit
• Adds "extracted" field to indicate if a particular file entry was emitted
• Adds "encrypted" field to indicate if a particular file entry was encrypted
• Configurable encrypted file extraction, as an alternative to ScanEncryptedZip
• Adds proper support for aes256 encryption
• Adds support for mixed encryption types in the same archive
• Changes password field to array

New configuration options:

        size_limit: 250000000
        limit_metadata: True
        crack_pws: False
        log_pws: True

New flags:

• file_count_limit
• file_size_limit

Oh I love this. I'll give this a test today. Great work!

@ryanohoro style check failed. I can clean that up if you'd like.

Cleaned up the styling (@ryanohoro black 24.x comes with a few changes)

Tested this locally and everything looks great. Much better output + functionality, thank you :)
