Software appears to be excluding all the products associated with the collections

[jordanpadams]

Describe the bug
When running deep archive on this EPOXI bundle (pds-gamma:/data/local/starbase/data/pds4/test-bundles/pds4-epoxi_mri-v1.0) all the data files under hartley2_photometry/data/ are missing.

To Reproduce
Steps to reproduce the behavior:

1. Download the data from above
2. Run pds-deep-archive -s PDS_SBN -b https://pdssbn.astro.umd.edu/holdings/ pds4-epoxi_mri-v1.0/bundle.xml

Expected behavior
the SIP and AIP should contain all the product references in pds4-epoxi_mri-v1.0/hartley2_photometry/inventory.csv

Note some of the weirdness with this bundle:

• There is an overview.xml in the same directory as collection.xml so we need to make sure that file is included.
• There are data and document sub-directories that both contain data from the inventory.csv (this is horrendous archiving, but it is what it is)
• pds4-epoxi_mri-v1.0/hartley2_photometry/document/epoxi_photometry_v5.[xml|pdf] should actually not be included in the SIP/AIP because its LID does not match the LID in the inventory file

Update: It appears the software is only outputting bundles/collections and not any of the associated products. It appears all the files are getting written to the database, just not the AIP/SIP.

Note to self (i.e., @nutjob4life): we parse for "P" lines in any <file_name> so long as the root element is a <Product_Collection>. We don't have to key off of .tab files like we currently are doing.
