fix: Prevent creation of duplicate bone children

Checks for suffixes "_end" and "_Tail" in the name of a bone, then doesn't create child bone if there already is one of the aforementioned suffixes.

It also looks for an "_end" tail because Blender armatures might import into Roblox with a bone child already created with an "_end" suffix (if it was exported with that setting enabled) https://blender.stackexchange.com/questions/109972/fbx-export-bone-end
