PEC Conformal Mesh Spec

tidy3d.StaircasingConformalMeshSpec	Simple staircasing scheme based on [Taflove, The Electrical Engineering Handbook 3.629-670 (2005): 15.].
tidy3d.HeuristicConformalMeshSpec	Slightly different from the staircasing scheme: the field component near PEC is considered to be outside PEC if it's substantially normal to the interface.
tidy3d.BenklerConformalMeshSpec	Conformal mesh scheme based on [S.
