Can't run forestsim on Ubuntu or Windows

Nothing is printed to the screen on Ubuntu and on Windows, it keeps printing the ImportError:
print('This program requires the bext module, which you')
print('can install by following the instructions at')
print('https://pypi.org/project/Bext/')

I tried spinning up a virtual env but same results.

Start by reproducing the forestsim behavior on Ubuntu and Windows, then inspect the reported ImportError and the bext installation path. Done means the program produces its expected output on both platforms without reporting that the bext module is unavailable.
