Changes to make bits in packets accessable to help protocol detection

Changed callbacks to include bits in packet, also shown in output.

Now we can also check bits to determine if this is a packet we want or bail out.

For weather stations it still is a drag as it seams that they use some alike format but different interpretation of the fields. So no proper detection possible there :-(. What we can do however is perhaps include a config file reading what unitname/devicenumber has protocol x.... but that presumes you know what unit numer it holds...

So please comment on this pull request....
