Log telemetry info

[NaN]

Nope. I usually just add an ofstream here and there to log stuff I am interested in.

But yeah, it would be great to have a way to log it without hacking vdrift.

The simplest variant would be to just log every sim step (90Hz), which might be quite a lot of data. Although we might get a bit more fancy and add options to log at every nth step and be able to select what to include in the log: powertrain, wheels, aerodynamics...
