Generalize Analysis Class

This MR is aimed at generalizing the analysis class to make bdaq53 fit for future chip support. Therefore a chip_type was added to the run_config tab in the raw .h5 file, as well as the first part of chip specific analysis functions moved to a dedicated rd53a_analysis.py file. In addition to that utils in the simulation setup was stabilized by adding relative paths for unisims and secureip based on the bdaq53 installation directory.
