More `tbc_timer_deviations` required to get information about the clock drifts

The tbc_timer_deviations of the clock of the communicating SC are used in the Kalman Filter to synchronize the clocks with TCB.

But we also need information about the linear and quadratic drift of that particular clock (USO frequency offset and USO linear frequency drift). In reality this information is available because after a few weeks we can just fit the timer deviation measurements (they come in once per telemetry contact ~ day). However, for the simulation this means that we have to simulate weeks of phasemeter data (and later on process it) only to get those few timer deviation measurements, which is unfeasible.

Instead I would suggest to decouple the simulation of the tcb_timer_deviations from the simulation of the phasemeter data, so that we can just simulate let's say 20 days of tcb_timer_deviations before the simulation of the phasmeter data starts.
