* wagyu: drop a hole no remaining ring can parent instead of throwing correct_tree() throws "Could not properly place hole to a parent" when topology correction leaves a hole whose parent ring was removed (degenerate input such as stacked duplicate rings from coalesced tiny-polygon placeholders). That aborts the entire tiling run over one unrepresentable sliver. Remove the ring and its points instead, matching how other unresolvable degeneracies are handled. * Add a regression test for dropping an unplaceable hole A fuzzer-minimized pair of mutually reversed self-intersecting rings that makes wagyu's correct_tree fail to find a parent for a hole — the same failure reported in mapbox/tippecanoe#761. Before the topology_correction change, running this test exits with EXIT_IMPOSSIBLE via the polygon cleaning error handler; with it, the clean returns.
