Describe the Feature Request

Unlike the original MapBox Style spec, the MapLibre Style spec now supports multiple sprites. Specifying multiple sprites should be supported.

Describe the Use Case

When a larger number of icons/symbols are needed, it is easier to manage them in a modular way in multiple sprites.

Describe Preferred Solution

In addition to the URL value, support an array with objects with id and url members. See https://maplibre.org/maplibre-style-spec/sprite/#multiple-sprite-sources
