Factory to which all modules register to on startup. Used by PELICAN to create Module from Config

See merge request !10

added unregister wrapper. I cannot do a pre-check if the module exists because I cannot access the private static member variable. I did not fully understand why. I have to make the private member variable inline, then I can access it. However, then the auto registration of the modules does not work anymore (because then the init of the variable is not dynamic anymore? or something like that?). Hence, I just made a simple wrapper.

added note to function description and cleaned up function name such that doxygen auto links to correct function.

- changed PPE_Config to use the BaseModules instead of ModuleBase structs - the automatic python gen reordered for some reason, thats why ppe_config.hpp has many more lines changed.

- added try catch note if no modules in factory

Rewrote module factory. Everything static now. Self register modules. Comments added. bug fixes in .cpp

- added/corrected parameter for all currently implemented modules

- added createModule function
- added descriptions

factory draft implementation done. Should have all functions needed. Modules have to register. To be tested.

default modules. Currently needs local poly-scribe branch feature/optional-dicts - https://github.com/pingelit/poly-scribe/tree/feature/optional-dictionaries. @pascal_palenda

Merge branch 'feature/propParamExport' of https://git.rwth-aachen.de/ita/ITAPropagationModels into feature/propParamExport

changed utils arg function to return valarray of float instead of complex float. Also using transform instead of loop.

- source and receiver strings are mapped to ints for PPU
