update of pipeline to ctapipe 0.8
This merge request implements the following:
- update of the pipeline to use ctapipe 0.8 (except for utils classes and cleaning_analysis.py, which were done in !11 (merged))
- bug fix for issue #15 (closed)
- remove deprecation warnings to have a cleaner output
- cleaning up of the code.
When merged, it closes #15 (closed), #16.
For the moment it is a WIP, while the code is reviewed, we should try out the whole pipeline again to check that everything works fine. After that, the WIP status can be removed and the code merged into master.
