updateTimeDimension only works when layer is queryable

[pineapplegum]

Hi, thanks for a great library! By looking at the source code, it seems like the updateTimeDimension = true will only work if the layer is set as queryable=1 in the getcapabilities. If it is set to 0, no times are returned. Is it somehow possible to bypass this and use updatetimedimension on non-queryable layers?

A hack/workaround would be to replace the parsing function.

This is a copy of the original without the 'queryable' requirement :

let parseTimeDimensionFromCapabilitiesFix =  function(xml) {

      //// old selector
      //// var layers = xml.querySelectorAll('Layer[queryable="1"]');

      //// new selector
        var layers = xml.querySelectorAll('Layer]');


        var layerName = this._baseLayer.wmsParams.layers;
        var layer = null, times = null;
        layers.forEach(function(current) {
            if (current.querySelector("Name").innerHTML === layerName) 
                layer = current;
        })
        if (layer) {
            times = this._getTimesFromLayerCapabilities(layer);
            if (!times)
                times = this._getTimesFromLayerCapabilities(layer.parentNode);
        }
        return times;
}

Then replace the parser after creation :

let wmsTimeLayer = L.timeDimension.layer.wms( ... )
wmsTimeLayer._parseTimeDimensionFromCapabilities = parseTimeDimensionFromCapabilitiesFix;
