/**
* Processes the Bulgarian National Corpus (BulNC) — general subcorpora.
*
* Unlike MARCELL/CURLICAT, BulNC metadata is supplied via an external
* tab-separated description file (BulNC-description.txt) rather than
* inline CoNLL-UP comments. Plain-text source files are read directly.
*
* Subcorpora included (controlled by {@link #isIncluded}):
* A-Administrative, B-Science, C-MassMedia, D-Fiction
* (edit the method to adjust the filter)
*
* SETimes articles are excluded regardless of subcorpus.
*
* Licence rules:
* A-Administrative → CC0
* B-Science → Restricted
* C-MassMedia → Restricted
* D-Fiction → Restricted
*
* Description file column indices (0-based):
* 0 filename stem | 1 relative path | 2 collection date
* 4 author | 8 title | 9 publication date
* 12 url | 13 translated | 17 type
* 19 domain | 21 subdomain (optional)
