[RPF Explorer] Bound composite children embedded in YDRs do not get the correct PolyFlags when exported

[Tim-R]

Codewalker version: 30_dev45

When exporting a YDR with embedded bound composite children (Bound Box in this case) that have Poly Flags (FLAG_TOO_STEEP_FOR_PLAYER [8192] in this case), the resultant PolyFlags in the .ydr.xml (`Drawable->Bounds->Children[0]->PolyFlags) is not correct.

Below is the ODR .bounds showing the PolyFlags including FLAG_TOO_STEEP_FOR_PLAYER, the YDR in question, and the bound item from the .ydr.xml. In game, FLAG_TOO_STEEP_FOR_PLAYER is applied and works as expected.
