[Feature Request] Modpack Updating

[sarpuser]

I would like to request a feature in which the mcman import mrpack or mcman init --mrpack uses the modpack URL instead of the URL to the direct download. This would download the latest available release. Additionally, there could be another switch such as --modpack-version <version_number> for downloading a specific version of the modpack. Finally, a mcman update mrpack can go to the modpack page and pull the newest version. This can also be extended to update individual mods/plugins by using mcman mod/plugin update <id>.

the next version of mcman is going to get rid of having addons inside server.toml and instead have a list of "source"s where each source can either be a toml file with addons like before or a modpack (local or remote) - with this design implementing this functionality will be much simpler (the v2 branch of this codebase includes much of this, i havent gotten into adding the update logic though)
