@M1chaelM @caguero can you take a quick look at this?

@j-herman @caguero Following the discussion in #426, it looks like we decided not to make this change and instead document the convention we're using here, so I'm closing this PR. Please re-open if I've misunderstood.

@M1chaelM can you just quickly update the wiki with the change?

I added some clarification to the wiki - please let me know if it's not clear.
New text reads:
"Bearings are reported in the WAM-V frame and coordinate system: the x-axis is towards the vehicle’s nose, the y-axis is towards the port side, and the z-axis points upwards. Following the right-hand rule, bearing angles are measured counter-clockwise beginning from the x-axis. "
