WIP sercomm implementation

- moved some module-specific constants to their respective header files
- changed .clang-tidy to ignore global private global constants
  (starting with `_`)
- suppressed some GCC warnings in bin.c and all pololu library warnings
- added function signatures for sercomm protocol data generators
- added endianness check in setup.c
