- replace size_t with uint32_t to fix an uninitialized data bug on arduino
caused by the fact that size_t is 2 bytes on arduino, but 4 bytes in
the ros message standard, which left 2 bytes uninitialized, containing
random data which may or may not cause a problem for any given program
and run on a given chip
