Performance improvement

[kaosat-dev]

Right now , very large/ complex amf files take a huge amount of ram and time to load:
this seems to stem from uneficient xml parsing:
(for example : https://www.youmagine.com/designs/robot-ice-winter-is-coming)
what needs to be done to solve this:

• investigate issue more closely
• perhaps switch to a purely js xml parsing solution (bonus: would enable parsing to take place in web workers)
