feat: check Python package "pyswmm"

[mrustl]

More people contribute to pyswmm compared to swmmr, which we currently use in different projects.

However, pyswmm could be also accessed from R via the reticulate R package.

Using pyswmm would improve the readability of the code e.g. for LID definition which is cumbersome with swmmr (e.g. LID parameters defined by their column position instead of their names: https://github.com/KWB-R/LIDsensitivity/blob/master/sensitivityAnalysis.R#L85):

DLL load Error occing in case of importing pyswmm is shown here:

Is probably related to problems in R package reticulate to deal with different Cindy environments/Python Versions:
