[Feature]: ASI loader should check Starfield folder for ASIs first

[gir489returns]

The legacy ASI loaders original plugins used to have the player to deposit the ASI files into Steam\steamapps\common\Starfield folder. The plugin should iterate the entire root folder and subdirectories looking for ASIs and alert the user that they are not in the right folder the plugin expects, as I was initially confused to why my ASIs were not being loaded, the only clue I could find was

# The relative path to the directory to load .asi/.dll files from ASILoaderRelativePath: SFAE ASIL

It wasn't until I looked at the source code did I understand what this means, it's relative to the Starfield directory.
