› Decoded payload for counting rotations (v2)

Decoder outputting general information and specific rotation and orientation data

Fixes from '› Decoded payload for counting rotations':

• For the field nfcState, the values"NFC_READ_ONLY" & "NFC_OFF" were swapped.

This decoder also decodes Geolocation and Local Gateway data.
