Make resource pack generation happen in the background

[MeltingDiamond]

Awesome plugin, but right now resource pack generation happens every time the server starts even when the models are the same as last server start. Which is slow with a lot of models. I was wondering if it was possible to make it generate in the background so the server can start faster.

Similar to this suggestion:

Can the reload be made fully asynchronous?

Alright so I closed that one because the core issue was dealt with. On the subject of async rsp generation, I am for it, it's just that I need to make sure such a system would then also send a signal for when the rsp is generated so it can safely be forwarded to other plugins (ResourcePackManager in the case of my specific suite of plugins).

So yes, I will add it, but it's not just a matter of making it async - I'll have to do some tinkering with MagmaCore and ResourcePackManager to coordinate it.
