* Fixed pedals calibration (apparently, this was borked for a long time)

* Asynchronous serial I/O

* Every serial device gets it's own I/O process

* Exclusive access mode for get/set commands

* Subscribtions can now be only single-shot

* BlockingValue class enables waiting for value read

* Discover commands from received data
