updated sample code with new function names

- breaking change: writeBit has been renamed to beginWriteBit to show it's asynchronous, and a new function writeBit has been introduced, which is synchronous and can't be called from an interrupt handler
...
- fixed possible bugs when a write operation is canceled and a timer interrupt is still registered

- breaking change: OneWireSlave::write has been renamed to OneWireSlave::beginWrite, to show it's asynchronous. A new function OneWireSlave::write has been introduced, which is synchronous (and can't be called from an interrupt handler)
...
- added code to make sure a client completion callback will always get called, even if it's because of a reset or an error

- 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)
