Scene Default Layer Mask Options

I found myself wanting a way to set a default layer mask in the scene such that I didn’t need to catch every mesh or other renderable object that was added to change its layerMask if I was trying to implement custom layerMask logic in my app.

Came across this forum Scene#defaultLayerMask
Which presented a good solution, so followed through on the idea proposed by the original author in a PR

Looking for feedback and/or approval on its implementation
