Hi,
I hit an (old) fixed bug with PS_KEY_PAUSE and read() return 0x06 instead of 0x05. IT was fixed by v1.0.10 but I never pull this version because I have used Arduino library manager, and it pools v1.0.9 at most.

May I ask you to publish it ? I will git pull from here instead in the meantime.
Thanks for the great work !
