 dbo.usp_sec_get_filing_metadata
============================================================================
 Given an accession number (adsh), return everything you'd want to know
 about the filing *before* pulling the statements themselves:

   Result set 1: the sub row (company + filing metadata)
   Result set 2: row counts per statement in pre   (non-dimensional)
   Result set 3: row counts per statement in num   (dimn>0 vs dimn=0)
   Result set 4: text fact count from txt

 Parameters
 ----------
   @adsh   accession number

 Notes
 -----
 * Text fact count (result set 4) will be slow on sec_fsnds unless you
   add IX_txt_sub (see sql/indexes/sec_fsnds_recommended_indexes.sql).
   Without that index the txt read is a full scan of 48M rows / 100 GB.
