Description
Support advisory speeds on segments
Overture currently only models regulatory speed limits (max_speed / min_speed in speed_limits). There is no way to express advisory speeds; posted recommended safe speeds, e.g. before sharp curves or on ramps.
These are conceptually the same kind of speed limit as regulatory limits (a speed value with a unit and scoping), so they belong in the core speed_limits structure rather than in an extension that would duplicate most of it.

Research direction
Start by examining the core speed_limits structure and how max_speed and min_speed represent units and scoping. Review linked pull request #556 for the current implementation direction; done means advisory speeds can be represented alongside regulatory limits without duplicating the speed-limit structure.
