fsoubelet/PyhDToolkit: Release 0.12.0

Release 0.12.0 brings the following: Added: A models module in cpymadtools to hold various pydantic models for data manipulated in the library functions. A query_beam_attributes function in cpymadtools.parameters that returns a parsed and validated MADXBeam with all BEAM attributes from the MAD-X process based on the currently defined beam. A ptc_twiss function in cpymadtools.ptc to conveniently create the PTC universe and perform a TWISS command according to the Ripken-Mais formalism. A ptc_track_particle function in cpymadtools.ptc to conveniently create the PTC universe and perform particle tracking similarly to cpymadtools.track.track_single_particle. A get_footprint_lines function in cpymadtools.tune to obtain the (Qx, Qy) points needed to plot the footprint based on the TfsDataFrame returned by make_footprint_table. To be considered experimental. A get_footprint_patches function in cpymadtools.tune to obtain a collection of matplotlib.patches.Polygon elements needed to plot the footprint based on the TfsDataFrame returned by make_footprint_table. To be considered experimental. The get_table_tfs function in cpmadtools.utils now takes a headers_table argument to choose an internal table to use for headers. Changed: The default energy value in cpymadtools.special.make_lhc_beams has been changed to 7000 [GeV] to reflect run III scenario. The value for npart in cpymadtools.special.make_lhc_beams has been changed to 1.15e11 to reflect run III scenario. The make_footprint_table in cpymadtools.tune now returns a tfs.TfsDataFrame instead of a pandas.DataFrame, the headers of which are populated with useful values for other functions. The beam_parameters function in cpymadtools.parameters has been moved to the optics.beam module and renamed compute_beam_parameters. The default patch.linewidth value in the phd matplotlib style has been changed to 1.5
