🎉 New Features
- New `.to_mat()` method to export the data downloaded to a MATLAB file, with the computation of the correct MATLAB time format.
👷 Bug fixes
- `spectrum.plot_1D_spectrum` no more plot the spectrum in polar coordinates;
- reduce default plot size in `spectrum.plot_2D_spectrum` and `spectrum.plot_1D_spectrum` and supress unwanted output
- in 'raw_compute_parameters_from_1D_spectrum' the CgE was not computed correctly and convert to kW/m
- in 'raw_compute_parameters_from_2D_spectrum': convert CgE to kW/m
- in 'spectrum/download_data': properly closes the connection
