If there is a small hole (smaller than the conn width), we can loop
around in a circle checking all points and not move past the mimimum
distance.
To avoid this, if we detect a loop, we exit the substantial checker.
This should return with true because a large hole will return true and
we are only checking to see if there is a minimum amount of copper
between two open areas
Substantial elements following a divot should be at least as far in each
cardinal direction from the origin point in order to be considered
substantial. This catches cases where the "substantial" element is
actually a straight segment away from the divot

Fractured polygons are always fractured along the x-axis, so when
checking to see if a segment is a fracture point, we check if the y
coordinate is equal. This avoids situations where there are multiple
fracture points between two inflection points
Additionally, we add a second check to ensure we don't hit spurious
blobs (all kinks should be symmetric and therefore be substantial in
each direction)

Nominally, the zcode of a vertex is unique. This is not 100% true,
however, as we must interlace two 32-bit numbers into a single 32-bit
number. Sorting needs to account for the possibility that the zcode
will be the same while other elements of the vertex are different. This
commit fixes the broken boolean logic to more clearly handle these cases

The connection width checker uses morton codes to order elements. The
sort should be primarily morton-based but needs to be stable in order to
ensure that nextZ/prevZ elements are properly placed as the actual
next/prev elements in the list. Otherwise, hitting a fracture point
might make us skip in the wrong direction

1) Move a bunch of std::map's to std::unordered_map to get constant-time
look-ups
2) Lengthen progress-reporting intervals to spend more time doing work
and less time talking about it
3) Reverse order of SHAPE_LINE_CHAINs in thermal intersection checks to
make (much) better use of bbox caches
4) Don't re-generate bboxes we already have
5) Fix some autos that weren't by reference (and were therefore copying
large datasets)
6) Rename delta progressDelta so it's easier to search for in future
7) Get rid of a few more autos (because I don't like them)
8) Pass large items to lambdas by reference

Since we aren't searching zones (they aren't in the m_CopperItemRTreeCache)
this will drop all errors that are zone-only (which are better handled by
zone-min-width).
