auto size single line cablearray to fit sectionarray in Section DataFrame

[adriengoeller]

Actual behavior: user has to do

cable_data = pd.DataFrame(
		{
			"section": [345.55],
			"diameter": [22.4],
			"linear_weight": [9.55494],
			"young_modulus": [59],
			"dilatation_coefficient": [23],
			"temperature_reference": [0],
		}
	)
cable_array = CableArray(cable_data.loc[cable_data.index.repeat(4)].reset_index(drop=True))
cable_array.data
#------
	section	diameter	linear_weight	young_modulus	dilatation_coefficient	temperature_reference
0	0.000346	0.0224	9.55494	5.900000e+10	0.000023	0.0
1	0.000346	0.0224	9.55494	5.900000e+10	0.000023	0.0
2	0.000346	0.0224	9.55494	5.900000e+10	0.000023	0.0
3	0.000346	0.0224	9.55494	5.900000e+10	0.000023	0.0

in order to have 4 identical cable for a section.

The idea is to add a .repeat method. This method can be used by the user in this way:

cable_array.repeat(n=4)
#------
	section	diameter	linear_weight	young_modulus	dilatation_coefficient	temperature_reference
0	0.000346	0.0224	9.55494	5.900000e+10	0.000023	0.0
1	0.000346	0.0224	9.55494	5.900000e+10	0.000023	0.0
2	0.000346	0.0224	9.55494	5.900000e+10	0.000023	0.0
3	0.000346	0.0224	9.55494	5.900000e+10	0.000023	0.0
