Subject: [PATCH] Add exception for Apple macOS result code type

Apple version of pcsc-lite library is slightly different from official one,
and defines result code constants in pcsclite.h as unsigned 32bit integers.
Official pcsc-lite version uses LONG type and it is traslated to signed long on most platforms.
This implementation difference is solved using pre-processor instructions.
