Parity in argument bytes sent from host #33

First of all, thank you for this nice piece of software.

I have been analysing the behaviour of this library using an oscilloscope, and I noticed that no odd parity bits are added to the argument bytes of a host command.
For example: using getScanCodeSet( ) the command is sent OK, but the following argument byte (0x00) does not get the additional 1 for odd parity bits.
I tried searching if this is the normal behaviour in the PS/2 protocol, but I found no such info.
So, I wonder if this is the correct behaviour or not.

I have a feeling that this might be the problem for the case of issue #23, but I might be mistaken.

Anyway, thank you in advance for any response.

PS: For what it's worth, I also cannot update this library to V1.0.10 through the Arduino IDE. It only gives me up to V1.0.9.

Regards,
Theodore
