Add get_firmware_version method

This patch combines the get_{major,minor}_firmware_version methods into
the new get_firmware_version method that returns a FirmwareVersion
struct.  Currently, this requires casting from i32 to u8.  But this will
be fixed with the next libnitrokey version as we change the return types
for the firmware getters.
