Feature request: Traccar-protcol: support for course/speed fields

Hi,

according to

https://github.com/tananaev/traccar-client-android/blob/master/app/src/main/java/org/traccar/client/ProtocolFormatter.java

traccar seems to sends fields containing speed + bearing information in its position data. It would be nice if those fields could be used and shown in phonetrack as well.

Thanks Micha
