Subject: [PATCH] Add type 'x' in Field::decode.

type 'x' means byte array (array of unsigned chars) so it is strictly not correct to return a LongString (array of signed chars). But with this change the library can continue going after receiving type 'x'. The original code crashes or starts doing undefined things when receiving a nonempty byte array from a client.
