Functions
unsigned char *	n_hex_decode (const char hex, size_t out_len)
	decode a hex string (ASCII whitespace between digits is ignored) into a freshly allocated, NUL-terminated byte buffer; *out_len receives the decoded byte count.
int	n_hex_decode_to (unsigned char out, size_t out_size, const char hex, size_t nbytes)
	decode exactly nbytes bytes from the first 2*nbytes hex digits of hex (case-insensitive, no embedded whitespace) into the caller-provided buffer out (needs out_size >= nbytes).
N_STR *	n_hex_encode (const unsigned char *data, size_t len)
	encode len bytes of data as a lowercase hex N_STR (2*len characters); free with free_nstr.
size_t	n_hex_encode_to (char out, size_t out_size, const unsigned char data, size_t len)
	encode len bytes of data as lowercase hex into the caller-provided buffer out (needs out_size >= 2*len+1), NUL-terminating on success.
