Make Nimue get its exploit parameters from configuration files

[CFSworks]

It would be nice if Nimue could accept configuration files (YAML? JSON? XML?) containing parameters (return address, stack size, etc.) for different versions of firmware, as opposed to hard-coding them in the .py... This would mean that supporting a newer version of the firmware only requires a config file update. The script itself should accept the version of the firmware as a command-line argument and load the necessary parameters.
