Say from_axes, which is what a constructor is called

`per_axis` on `PlaceDesc` and `Declared` builds a pair by asking for each
axis. `from_axis` beside it already names the three-argument form, so the
plural is the one that takes a function, and both follow Rust's convention
for a constructor rather than an invented word.
