oneshot option

[johnmerkelbach]

I am missing the one shot send option in this library , as i would like to use this library for a Time Triggered can bus .
It is not important that every MSG is acknowledged, as these are repeated every xx ms . so they don't have to be retransmitted.
for this option one shot mode is preferred .
this is done by setting the TWAI_RX_REQ and TWAI_ABORT_TX bits in the command register at the same time , at send command .

Is there a option to add tryToSendOnce to this library.
My C skills are not so good that i should try do this myself .
