Fluid slotSize cannot be assigned due to type coercion check

[masakikomine]

        if (Array.isArray(slotSize) && Array.isArray(slotSize[0])) {
            slotSize = slotSize[0];
        }
        // https://developers.google.com/doubleclick-gpt/reference?hl=en#googletag.NamedSize
        if (slotSize === "fluid") {
            slotSize = ["auto", "auto"];
        }

The above code in the render() of Bling.js cannot properly extract the value 'fluid' due to type coercion. For example the slotSize = [['fluid'],[1,1]] has slotSize[0] = an array object with the 'fluid' as it's 0th index value, but will evaluate to false against === "fluid" which is a string.

This could be updated to: if (slotSize === "fluid" || slotSize[0] === "fluid") and then the issue should be resolved.

You're right, this should be adjusted to handle the ['fluid'] case. PR is above if you want to review it.

Note that both 'fluid' and ['fluid'] are acceptable forms to declare a slot size as fluid. https://developers.google.com/doubleclick-gpt/reference
