incorporate drone parameters

Per Matt, 2/6/26:

Additionally, we now support the following parameters, and will render most of them in the UI. It's pretty simplistic, for example only showing the camera's azimuth out to a fixed distance rather than ray-tracing based on the drone's AGL and the camera's tilt, but we wanted to gather some real-world data so that we can assess the accuracy / usefulness of more advanced functionality prior to implementing it.

• aircraft:altitude (height above MSL in feet, if both elevation and altitude are specified, altitude wins)

• aircraft:altitude_rate (rate of climb in ft/min)

• aircraft:pitch (in degrees, positive is nose up)

• aircraft:roll (posiitive is left wing up)

• aircraft:gs (speed over the ground in knots)

• aircraft:heading (direction the nose is pointing)

• aircraft:track (direction of travel over the ground)

• camera:azimuth (angle the camera is facing, degrees true north)

• camera:tilt (up/down angle relative to horizon, -90 is straight down)

• camera:fov_width (horizontal field of view in degrees)

• camera:fov_height (vertical field of view in degrees)

• camera:external_url (link to an external website showing the camera livestream)

• camera:thumbnail_url (direct link to camera thumbnail image)
