Use register 5242 for high precision grid frequency (#372)

* Use register 5242 for high precision grid frequency Sensor was already set to precision 2 even though scale was 0.1. This way, the actual grid frequency fluctuation is visible. * Move sensor position to new position (ascending reg values) --------- Co-authored-by: mkaiser <[email protected]>
