v2.0.0

• ⚠️ breaking: publish polylabel as a ES module instead of CommonJS.
• ⚠️ breaking: drop support for IE11 (you can still transpile the code on your end to keep it).
• Prune cells more aggressively, slightly improving performance.
• Fix the algorithm getting stuck on some degenerate cases.
• Make sure the result is never outside the polygon even on low precision.
