Changes

• Add class GNSS
• Merges develop and fixes conflicts with new implementations (mainly pylint and FlightPhases refactor)

The noise parameters of the GNSS are much simpler than from the other sensors. I made it so because it seems that errors are taken into account as accuracy rather then noise densities in GNSS sensors.

I am not sure if the way its done is the most robust way of doing this, but it was what I gathered from research
