Allow to compile for the Arduino IDE again. See issue #3
Add schematic PDF for those chinese boards. See issue #3
sendData: Allow to set number of bits of last byte to transmit
Prepare for ISO-14443: WAK/WUP commands have a frame length of 7 bits
Default "validBits" is zero, so it does not break existing code
