Describe the change
Adding support for filename and size metadata extraction for MSI files using the ScanSevenZip scanner. This can be useful for observing additional file metadata from an MSI file rather than relying on the extracted files themselves, previously extracted by ScanLibArchive. This can be additionally useful if you're using something like Elasticsearch, where there is little relation between the records. With this approach, users can see that a file is an MSI file, the MSI file metadata, and the files that reside in the MSI file.

Includes:

• New .msi fixture
• Updated ScanSevenZip scanner to support file metadata collection that do not have datetimes.
• Updated tests for ScanSevenZip and ScanMsi to support the above changes.

Describe testing procedures
All tests ran successfully on build
