Level Streaming Level Order

[JWTechnical]

When generating the level streaming JSON file the levels appear out of order. They don't seem to respect either Alphabetical or the sub-level ordering in the levels tab.

I would be curious if this could become Alphabetical, that makes it really easy to order the levels appropriately so they will be seen in Disguise in a logical order.

Case Example:

[eclazi]

May break existing sequencing if the order is changed as keyframe stores an index into the list in d3

[husberg-disguise]

That d3 bug is internally referenced as DSOF-16571. I'll see if we can expedite it, but that shouldn't block fixing this.
