story-to-pack: add the corpora and the catalogue v2/v3

Fourteen corpora split and classified: aesop, bierce, chekhov, holmes,
keefe, lawson, lorimer, maupassant, nobody, plaintales, poe, torchy,
wallingford and winesburg, each with its splitter and the hand-written
groups and pages; catalogue v2 and v3; and the shared splitters
gutenberg_chunks.py, se_split.py and se_build.py.

+"""Split the Project Gutenberg text of George Randolph Chester, *Get-Rich-Quick Wallingford* (eBook #37010),
+one story per chapter. It is a novel of linked episodes: each of the promoter's schemes runs over several
+chapters, so for the recurrence rule the reader groups chapters into schemes (ARCS in claude/groups_src.py)
+and a situation must recur across schemes, not merely across chapters of one scheme.
+The body heads each chapter with a bare `CHAPTER <roman>` line followed by an upper-case title that may
+wrap; the headings must number 1..28."""
