make all the imports relative, so all this can be imported in python,…

… towards integration goals. add a __main__.py to RASP_support, that starts the REPL, so the module can still be used directly as a REPL, now by calling python3 -m RASP_support. update rasp.sh and tests/test_all.py to use this new call
