Expose remaining classes from decomposition or geometry modules

[Lucas-Haubert]

Given our needs in nanoeigenpy, remaining classes to expose:

• unsupported/Eigen,
• KLUSupport, SuiteSparseQRSupport, UmfPackLU, PardisoSupport, PaStiXSupport, SuperLUSupport,
• HouseholderSequence,
• Geometry/Transform, Geometry/AlignedBox
