TypeError in RothC_Py.py due to incorrect os.chdir() argument

[lrodrin]

Hi,

I noticed that os.chdir() function in RothC_Py.py is called with an incorrect argument, resulting in the following error:

TypeError: chdir: path should be string, bytes, os.PathLike or integer, not list

Problematic line:

os.chdir(["INPUT DIRECTORY PATH") # Change to path of RothC_input.dat

Suggested Fix:

os.chdir("INPUT DIRECTORY PATH") # Change to path of RothC_input.dat

Thank you for addressing this issue!
