New EpiAware infection generating process: generate from SciML.solve

          wow what if this was rewritten as an infection EpiAware infection model (new issue/PR)

The idea here is to make a new infection generating model which ingests some DEProblem and generates the infections from solve on this object.

Potentially this needs to wait for refactoring the infection submodule but also potentially could be done with it as it is and then have a later refactor
