ISO15693 CRC calculation is slow and it delayed too much transmission of long
frames. Some readers marked transmission as unsuccesfull and ignored data.
Moving CRC calculation inside the codec allows to start modulating the field
while the CRC is not yet ready but, by the time it has to be trasmitted,
calculation will be done.
This fixes https://github.com/emsec/ChameleonMini/issues/262
In EM4233, there still are issues with Read Multiple command when block
locking status is requested for more than 0x1F blocks
Implemented a check in ISO15693 codec to avoid out of bound CRC writes.
