Port EMT Assetmover implementation

[MasterEnderman]

In EMT I came up with an easy implementation for assetmover to utilize it inside a mod.

Definitely something I want in catalyx too as it saves me copying over a lot of textures for a possible future project.

It still should be a soft dependency so no hard crashes if it isn't present. Just an error message in the log.

I don't see a reason for this, the AM API is quite easy to understand and use, and all EMT does from what I can tell is read user config so other stuff can use AM just by configuring EMT. I don't see a need to duplicate that functionality into Catalyx.
Unless you mean some other functionality that I couldn't find?

I'm not talking about the user config stuff that stays in EMT. Maybe I should have be more specific, but this was more or less just a note to myself. The stuff I'm talking about is the

• load data from a file inside the modpack directory Reference
• the internal assetmover stuff I use for the boss bars, which targets a a file inside the mod resource directory, i know that this could be done solely in code, but I prefer having all the paths specified in a different file Reference
