[NF] DQ extension to DQH

[BonneelP]

Hello all,

We plan to extend the existing DQ transform methods to the DQH frame.

Best regards,

Hello,
We can add one dimension in the transformation matrix as follows. P =2/3 for keeping the amplitude, P=sqrt(2/3) for keeping the power. Inversely P'=1 for the amplitude, P'=sqrt(2/3) for the same power.

Best regards,

Hello, I share the voltage equations on the dq0 frame:

The dq transform has been extend to dqh in PR #464, in addition there are also new functions to directly apply dqh transforms to DataTime object, with tests (cf. test_dqh_transformation.py)) to check that pyleecan convention in terms of rotating directions (as explained in #468) is working, and also that other conventions are working well.

The functions were previously in Functions/Electrical/coordinate_transformation.py which has been renamed to dqh_transformation for more clarity.
