Commands:
'run'       - builds the fuzzing container and runs the fuzzer
'stop'      - stops the fuzzing container
'follow'    - prints and follows the log output of the fuzzing container
'clean'     - clean up the fuzzing environment (does not remove artifacts or the fuzz corpus)
'erase'     - fully clean the fuzzing environment - WARNING: this will remove all the results of previous runs"
