- added possibility to be notified of individual bits received
...
- fixed bug when sending individual bits or canceling a write operation
- DS18B20 sample now sends zeros during conversion, and ones when conversion is finished

- breaking change: global instance of OneWireSlave renamed from "OneWire" to "OWSlave" to avoid conflict with the OneWire master library in case someone wants both libraries in the same sketch

- fixed bug in Pin::attachInterrupt (this is an arduino bug : interrupts that have been triggered before the handler is attached will cause it to be called immediately ; but only interrupts happening after should call the handler)
...
- changed OneWireSlave interface to make it completely static (there is an instance, but it's only a wrapper to the static stuff, so that the syntax looks nice)
- the search rom algorithm works fine most of the time, but sometimes it fails, probably because of interrupts being blocked at the wrong time (small delay to respond to the master to send a zero)

more robust reset detection, now purely implemented in interrupts, that allows the match rom algorithm to work even if our rom is not the first one
