SPC 2020-2023 developments included in SimulinkWrapperGAM

• bug fix in byte array bus mapping (homogeneus mode not correctly handled)
• byte array bus map now works in uint8 type and native type, but this has to be tested again, there is at least 1 case in which it generates problems, see: https://gitlab.epfl.ch/spc/SPCIT/marte2-components/-/issues/2
• algorithm code description string retrieved and logged from the simulink code .so
• post config message send loop inserted
• 2 public methods added for working with MDSSPCWriter components
  • code description string getter
  • simulink port list getter
• all GAM tests passing on scd.epfl.ch with MATLAB2019a
• No additional tests added
• SimulinkWrapperGAM now works again with SPC specific components
• fix big bug in row-major / column-major conversion of model parameters and I/O signals
