Add current path when using `from_rev`

[PythonFZ]

I found that when using zndraw node.atoms --remote . when using src.Node as the node, I get an ModuleNotFoundError: No module named 'src'. The package might be available via 'pip install src'

This was fixable by running export PYTHONPATH="${PYTHONPATH}:<PWD>" before

need

import sys
import os

sys.path.insert(0, os.getcwd())

[PythonFZ]

or more specifically, when using remote=/... the modules from there should be somehow accessible, for a local path, we can sys insert them, when loading from remote this is more difficult.

Maybe also try to reduce the amount of dependencies that are being loaded to a minimum, e.g. to avoid
