There's an increasing amount of slow logged topics at 1-2Hz, which were all
updated in the same logger iteration, leading to data bursts. For log
streaming this started to exceed uart buffer sizes. By distributing updates
more equal over time those bursts are removed, reducing buffer size
requirements.
Tests showed during steady state a reduction of maximum topic updates per
iteration from 40 down to 17.
Also the SD log buffer fill level is more constant.
