Make logger a global object instead of an instance

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)
