on Windows and Macos, most filesystems are case-insensitive, which can lead to dangerous situations one example is when another program (not copyparty or its UI) wants to rename a file from `Foo` to `foo`; the program will probably start by checking if `foo` exists and then delete it, however this would match `Foo` and confuse the program into deleting the wrong file fix this by adding a VERY EXPENSIVE detector to prevent this, by listing the parent folder and checking if the case matches this check will auto-enable when a case-insensitive FS is detected on startup, but option `casechk` (global or volflag) can override this
