If we dont explicitly check for pyserial, we can have the case where the
import works but the Serial object creation fails. However, we don't see
this because we have this huge try/catch block which swallows
everything.

With a DLPF of 62.5 Hz, the sampling rate is apperently not 1 kHz anymore,
because the driver got duplicate samples and published only at 128 Hz.
We have to increase the filter back to 500 Hz so that we get 1 kHz sampling
rate, with 250 Hz publications.
