Add directory argument to Set-LocationFuzzyEverything()

This allows setting an initial directory filter on what Search-Everything
returns, making it more versatile as it allows starting the search in
another directory than the current one and makes it a much faster alternative
to Invoke-FuzzySetLocation: for a directory with about 10000 subdirectories,
`cde somedir` is instant while `fd somedir` takes 10 seconds.
