Some tests fail locally because of the "/work/" absolute path

[bogdantoader]

The absolute path "/work/" in the config files used by the Jupyter notebooks causes the test_notebook to fail when ran locally.
This should be replaced with a relative path, but to do this, the constructor of tem.TEMSimulator should take the config as a dictionary rather than a path

Thanks @bogdantoader for looking into this! I'll work on a fix
