protodune wire geometry v3 has order errors

[brettviren]

Induction wires with segment 1 are wrongly ordered in protodune-wires-larsoft-v3.json.bz2

The intention is that all wires are always ordered such that (wire)X(pitch) = (face normal) where normal points into the drift volume (ie, anti-parallel to drift direction).

The v3 sorting used the simple assumption that wire-center should increase in (local) Z. This works for MB but fails on segment-1 wires in DUNE SP as the segment-1 wires have degenerate Z values.

This bug will hit any code that relies on this ordering. In particular, fast spatial lookup of nearest wire in the sim and similar calculations in imaging.
