Make the "totally digested" instadeath timer much faster

Browse Source 
This is one of the fairest instadeaths in the game (it gives
multiple warnings and there are reliable ways to escape it), but
is also where most of the threat of purple worms comes from. It
was also pretty much nonfunctional: the previously used formula set
the timer to somewhere around 50 turns (for a typical character in
Gehennom, which is where purple worms are normally encountered).

This new formula (which affects only purple worms, as the only
monster that engulfs and digests) is based on the same inputs, but
produces much smaller numbers, meaning that the instadeath is
relevant sometimes. A typical character at purple worm depth will
be able to kill faster than the timer if they focus on the purple
worm and put some damage on it before they get engulfed, but it is
much closer if the purple worm gets the first hit in (possibly
requiring the use of escape items, but the common wand of digging
works).

Hopefully this brings purple worms closer to their intended threat
level: previously they were somewhat more nonthreatening than they
should have been.
