plot geometry for dispersive materials without initializing structure…

… object (NanoComp#1827)

* plot geometry without initializing structure class

* update docstrings

* rotate epsilon grid by 90 degrees to properly orient axes

* add support for dispersive ε

* update markdown pages from docstrings

* make frequency and resolution parameters of plot2D dictionary keys of eps_parameters

* reinstate frequency parameter of plot2D and add warning that it is deprecated

* fix order of frequency check
