Apparently when no tty is attached, which is the case for Docker, the
buffer size for stdout increases to the point that only half of the
entire log might be written.
Passing Logger object into every function isn't fun. See for yourself:
something as simple as a public key printing function turns from
>void print_public_key(const uint8_t *public_key)
to
>void print_public_key(Logger *logger, const uint8_t *public_key)
