bug fix from Horst Steuer to fix ZpandasPickleWarning

COMPASS V5 release

        PEP 8 application in shesha.supervisor
        PEP 8 style in carma / sutra
        Add CUDA 11 support
        Make MAGMA an optional dependency
        New supervisor architecture using components and optimizers
        Remove get_centroids --> becomes get_slopes
        Old behavior of get_slopes was to call compute_slopes, which compute and return. Directly use compute_slopes instead
        Remove get_all_data_loop functions from abstractSupervisor and AoSupervisor : unused
        Remove computeImatModal from AoSupervisor : not used and not implemented
        set_gain was able to set mgain also depending on the parameter given. Change the function to be more explicit : set_gain only set scalar loop gain while set_modal_gain set the modal gain vector
        Rename set_mgain to set_modal_gain
        Rename get_mgain to get_modal_gain
        Remove write_config_on_file from AoSupervisor, and rename it getConfigFab in canapassSupervisor
        Rename set_global_r0 to set_r0
        Rename getIFsparse to get_influ_basis (to make difference with get_influ)
        Rename getIFtt to get_tt_influ_basis
        Rename getIFdm to compute_influ_basis
        Remove getTarAmpliPup (unused)
        Remove reset function, use reset_simu instead
        Remove setModalBasis : unused
        Remove computePh2ModesFits : unused
        Rename setPyrSourceArray in set_pyr_modulation_points
        set_pyr_modulation becomes set_pyr_modulation_ampli
        Signature changes in setPyr*Source : wfs_index first is mandatory
        Add new parameter in PWFS : p_wfs._pyr_scale_pos to store the scale applied to pyr_cx and pyr_cy before upload. Useful for Milan functions
        Rename recordCB in record_ao_circular_buffer
        Signature changes for set_fourier_mask, set_noise, set_gs_mask : wfs_index as first argument and mandatory
        Remove compute_wfs_images : not used
        Rename set_dm_shape_from into set_command
        Add new parameter in PDMS : p_dms[0]._dim_screen to store the dimension of the DM shape screen
        Add components module : this module defines classes to handle implementation of AO components such as Wfs, Dm, Rtc and so on. For now, only compass implementations are coded, but an abstraction for each component will be developed to allow third party library implementation
        Add optimizers module : this module defines classes to operate on the supervisor components for AO optimization. It could include many algorithms, define in some “thematic” class. For now, it includes ModalBasis class (for modal basis computations) and Calibration class (for interaction and command matrices). User defined algorithms that do not fit into one of those classes should be written in an other new class with an explicit name to be used by the supervisor.
        Remove abstractSupervisor
        Remove aoSupervisor
        Remove the simulator module : methods have been moved into the right component
        Add CONTRIBUTING.md file to define code guidelines
        Add unit tests for each method accessible from a compassSupervisor using pytest. Each contribution should define a new unit test
        Add templates for issue and merge request
