day 17 fix cost calculation
...
i was accidentally using the previous coordinates to calculate the cost
for each node, which means the A* search was effectively calculating the
cost of the return trip instead of the forward path.
doesn't affect the path at all - the start and end nodes are fixed, so
it doesn't matter whether their costs are included or not - but it does
mean that the cost being returned at the end was off by ((value at end
point) - (value at start point)) compared to the expected value.

day 16 cleanup
...
switch to globals (passing array names around is ugly).
(maybe look into dicts sometime?)
also, properly detect width/height from the input
instead of hardcoding it

tcl's dict type is exactly what we need for this problem:
an order-preserving de-duplicated list of key-value pairs.

i also tried getting rid of the 'next' dict and just keeping track of a
boolean of whether we changed anything on each pass, but that made it
slower somehow. cache effects i guess?

slightly more idiomatic tcl?
...
lmul is a more idiomatic name than product.
using join+eval is probably slower than foreach but the lists are small
so i don't care.
