Complete basic functionality (i.e. retrieval of function pointer and execution with arguments). Needs more testing and safeguarding against corrupted messages

Solve the pointer storage problem to the map, storing them as void*. Retrieval tested with explicit casts, now looking for a way to store type information of functions in a retrievable way

Make clang-tidy happy again, attempt #1

Attempt #2 at calming down clang-tidy

Add a basic wrapper struct for function argument handling

Pacify Vera and (hopefully) cppcheck
