Asset sync toggle to optionally ignore assets within systems/modules

[rikmarais]

Often, premium modules and systems may have a lot of assets stored in the Assets Library in these folders. Since these assets will usually be recreated when installing the relevant packages on local Foundry and can slow down the sync, add an option to ignore these folders and let the package install recreate them

[kakaroto]

Yeah, good point. Should probably warn if the module isn't installed though, and have an option to "sync assets from this folder anyway" or something along those lines, instead.
Unless it's a persistent storage file.
