load Style Pack
Loads a new style package or updates the existing one. If a style package with the given id already exists, it gets updated with the values provided to the given load options. The missing resources get loaded and the expired resources get updated. If there no values provided to the given load options, the existing style package gets refreshed: the missing resources get loaded and the expired resources get updated. A failed load request can be reattempted with another loadStylePack() call. If the style cannot be fetched for any reason, the load request is terminated. If the style is fetched but loading some of the style package resources fails, the load request proceeds trying to load the remaining style package resources.
