DeprecationWarning in import_file on tabular tests about oemof-tabular

[MaGering]

It seams that pyomo=6.0.0 does not need PyUtilib anymore. So a way of "fixing" this would be setting pyomo to 6.0.0 and uninstalling PyUtilib. I would therefore leave it as it is. As soon as oemof.tabular runs with a higher version of oemof.solph the problem should be solved.

After installing and testing tabular i receive a DeprecationWarning:

* lib/python3.8/site-packages/pyutilib/misc/import_file.py:11: DeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses
  import imp

This is caused by pyutilib. Seems that pyutilib has not released since 2020. TODO: Find out which dependency uses pyutilib

Find out which dependency uses pyutilib

oemof.solph==0.4.0 uses pyomo >= 4.4.0, < 6.0 which installs PyUtilib==6.0.0

Thanks for checking, @MaGering. Can we fix the warning with a newer version of pyutillib? Or shall we leave that to pyomo?

[jnnr]

Sounds reasonable. Will be fixed as soon as a newer oemof.solph allows newer pyomo.
