[Feature Request] Support for installing modpacks

[mooziii]

e.g. installing All of Fabric 5 through pacmc

This is definitely planned!

I am already working on this (there a couple of things to it). As modpacks aren't just a list of mods to install, but also consist of configuration files and Minecraft settings etc, they need to be applied on a "Minecraft instance" level, and not just a "folder level" (as the current archives are).
This means I first have to develop Minecraft instance support, and then modpacks can be supported.

Additionally, Modpacks come in various formats, and each of them needs to be implemented separately.
