v0.4.3

• The triangle package is now an optional dependency instead of a mandatory one.
  • This decision was made because triangle cannot be installed on MacOS with the M1/M2 chipset. See #18 for more details.
  • The sketch cleanup and line fit operators can be used without triangle. The output is expected to be the same.
  • The mesh generation operator can be used without triangle. However, some options of the "Delaunay Triangulation" mesh style will be invalid. The "Grid" mesh style is not affected.
  • Please refer to the wiki page for the latest requirements of the dependencies.
