Add Globe wind direction method to RACE_DATA.wind_direction_methods

Add Wind Direction Method Code to RACE_DATA.wind_direction_methods: Globe
Research team making the request @vszalay

Hi Ned and Duane, PVS asked to have globe added as a code to RACE_DATA.wind_direction_methods.
I wanted to run it by you before adding it. What say you?

@vszalay Paul-explain how guestimating wind direction using Globe as your compass differs from using the gyro compass on the dash (which we already have a method code for). Or, explain what I'm missing about how you use Globe to come up with wind direction. I'm presently hesitant to add this method code unless it's materially different than using a compass to figure out wind direction but not entirely opposed given good reason to the contrary. Put another way, we could change the gyro compass method to "compass" and get the same result, right?

@Laman I have personally never looked at the gyro compass (OK, maybe a long time ago) to figure out wind direction. I look at where the waves are coming from relative to the boat and then look at globe (where both the vessel orientation and the direction it's going in is displayed) to translate the observed relative direction between the wind and the boat into an absolute wind direction. I hope that makes sense.

Thanks, Paul. Yes that makes sense.
Let me think on this some more. Maybe there's some value to logging the technology creep experienced over the history of the survey so that we know back when we used the gyro compass but now we're translating GPS streams into a compass of sorts to get the same direction guestimates.
Happy to hear other thoughts on this topic.
