Update setup.py to resolve missing packages error upon install

[amrtini]

I got the following error upon install:

(c:\Users\x\Documents\dev\mike\.conda) PS C:\Users\x\Documents\dev\mike> pip install simradrain

  note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

× Encountered error while generating package metadata.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

I changed the packages in setup.py since the specified packages are python modules.
Thanks for making the code public!
