Track symbol has a very long line (leader for course)

[alexhuynh7]

The track symbol's course line becomes very long when zooming in (Leaflet zoom level 2). When I zoomed out (Leaflet zoom level 10), it became normal again. No idea how to make it shorter while zooming in or have a consistent length.

The leader line shows how far the vessel would travel in the amount of time specified by leader time. It shows the relative speed of a vessel.

The leader line is affected by:

• https://org-arl.github.io/leaflet-tracksymbol2/typedoc/classes/TrackSymbol.html#setSpeed
• https://org-arl.github.io/leaflet-tracksymbol2/typedoc/interfaces/ShapeOptions.html#leaderTime
• https://org-arl.github.io/leaflet-tracksymbol2/typedoc/interfaces/AISTrackSymbolOptions.html#leaderTime

If you wish to shorten the leader line when zooming in, you can reduce leaderTime (defaults to DEFAULT_LEADER_TIME = 60s).
