Spectral Index: Replace `struct`s of `enum` with Class (#2062)

* Add New Spectral Index Class

* Cleaning

* Use New Spectral Index Class in PML

* Cleaning

* Reuse Available Data for divE

* Allocate Rho Data Only when Necessary

* Cleaning

* Fix Bug in RZ Geometry

* Revert Commits for Allocation of Rho Data

* Cleaning

* Update Forward Declaration Header

* Do Not Include Unnecessary Header Files

* Doxygen

* Do Not Use Separate div() Cleaning Flags

* SpectralFieldIndex: Add Missing param to Doxygen

* Remove Unused getRequiredNumberOfFields
