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 plain text of *The Works of Edgar Allan Poe, Volume 2* (Raven Edition,
+eBook #2148) into its 22 tales, then cut scenes with the same rule as ../chunk.py,
+../jacobs/split_se.py and ../wharton/split_gutenberg.py (paragraph boundaries, ~320 words, tail >= 80).
+Deterministic: titles are the 22 contents entries, matched as whole upper-case lines after the
+contents list. Header lines differ slightly from the titles (trailing periods, a curly apostrophe,
+"MAELSTROM" without the ring, "SILENCE—A FABLE" with no spaces), so both sides are normalised before
+matching. Front matter, the contents, the redactor's note, the "Notes to the Second Volume" and the
+Gutenberg licence are dropped. Poe's footnote markers ("(*1)") are left in the text as split."""
