Review comment:
libcbor already seems to take care of any byte order issues on decoding: https://github.com/PJK/libcbor/blob/master/src/cbor/internal/loaders.c (it would be very surprising to me, if it did not), so these are unnecessary.
I know these have been copied from MiNiFi code, but the runtime check for endianness and manually writing byte order transformations are horrific.
There are compile-time checks for endianness and the ntoh* and hton* family of functions that automatically take care of these conversions.
