When creating an empty network, the sourceFormat attribute is empty whereas its use is required

[gaouizer]

Describe the current behavior

when creating a network via the network.create_empty() function, the created network has an empty sourceFormat attribute and it does not seem that a setter is available. Thus, when dumping the corresponding network to an iidm xml file with network.save(), the sourceFormat attribute of the network tag is empty whereas the use of this attribute is required in iidm format. The resulting iidm file is not usable as such with some other powsybl tools such as iidm4cpp which raises an error in that case.

Describe the expected behavior

a non empty value shall be given to this attribute (either a default or via a setter)

Describe the steps

import pypowsybl as pp
network = pp.network.create_empty()
network.save('test.iidm')

A non empty source format is not required in the Java model. The issue is problably on IIDM C++ side.
