This removes set_debug_mode, see breaking changes section

Breaking changes

Specifying an empty attribute list now returns a dataframe with no columns (#365):
network.get_***(attributes=[]) is not equivalent anymore to network.get_***()
pp.set_debug_mode(True) does not exist anymore and is replaced by the integration to python logging framework.
All pypowsybl logs are written to the logger named powsybl. You may configure the log level as for any other logger:
```

PyPowSyBl - v0.13.0

PyPowSyBl v0.13.0 Release Notes

Features

Support for PowerFactory file import (#329)
Network area diagrams can now be created around a list of voltage levels, instead of just 1 (#327)
breaking change: the argument is in consequence renamed from voltage_level_id to voltage_level_ids:

network.get_network_area_diagram(voltage_level_ids=['VL1', 'VL2'], depth=2)

A per-unit view of the network is now available: pypowsybl.perunit.per_unit_view(network) (#193)
Network data
- The location regulated by the voltage control of generators is now available as regulated_element_id attribute (#218)
  For now, it is only supported in node breaker voltage levels.
- Network elements creation (#259, #319)
- Dataframes elements selection (#283, #311, #312)
  breaking change: in order to get columns corresponding to properties in IIDM, you now need to use the argument all_atributes=True:
```
network.get_generators()  # Only gets default columns, which does not include IIDM properties
network.get_generators(all_attributes=True)  # Get all possible columns
```
- Missing lcc dataframe update (#321)
- breaking change: for better consistency between dataframes, all attributes ending with ..._setpoint have been renamed to target_.... For example voltage_setpoint becomes target_v (#282)
Update powsybl components (#326):
- powsybl-core 4.7.0
- powsybl-sld 2.8.0

Linting (#308)
Fix code coverage generation for sonar (#294, #297)
Use official GraalVM GitHub action (#292)

Breaking changes

By default, not all columns of network dataframes are now returned by getters:
in particular, IIDM properties are now considered "non default columns", and you need to either ask for all attributes
or for the specific attributes you need:

network.get_generators()  # Only gets default columns, which does not include IIDM properties
network.get_generators(all_attributes=True)  # Get all possible columns
network.get_generators(attributes=['target_p', 'my_property'])  # Get only target_p and my_property columns

for better consistency between dataframes, all dataframe columns ending with ..._setpoint have been renamed to target_.... For example voltage_setpoint becomes target_v.
Network area diagrams can now be created around a list of voltage levels, instead of just 1,
the argument is in consequence renamed from voltage_level_id to voltage_level_ids:

network.get_network_area_diagram(voltage_level_ids=['VL1', 'VL2'], depth=2)
