[bug] Deprecated numpy attribute in CIM Converter

[wenglerjoe]

Problem Description

When trying to open a CIM file using the from_cim.from_cim function in the pandapower converter, I receive an AttributeError that module "numpy" has no attribute 'typeDict' ...\pandapower\converter\cim\cim_tools.py", line 38, in extend_pp_net_cim np_str_type = np.typeDict.get('str')

Apparently, typeDict has been deprecated and replaced with scttypeDict.

What steps reproduce the problem?

1. Fresh install of python environment
2. import pandapower and from_cim function from pandapower.converter
3. Open CIM file (.zip file) using the from_cim.from_cim function

What is the expected output? What do you see instead?

Successfully opens CIM file and stores it in a pandapower net object.

Above was done in Python 3.10

Solution (for now): Python 3.9: installing numpy==1.21 which still supports the above function.

@wenglerjoe The bug is fixed now, have a look at PR #2005
