Update how the Q8's GPS fix status channel (LFT) is plotted

The Q8's GPS fix status channel (LFT) has a lot of different value (0-9), and so plotting it like other GPS fix status channels will be difficult. After some discussion with Alissa, it has been decided that similar points will be grouped together, creating 4 groups in total.
