[On hold] Support `Outside Folder, with Same Name` mode for Folder Notes

Can you please support Outside Folder, with Same Name mode from https://github.com/aidenlx/alx-folder-note/wiki/folder-note-pref as well. All my notes are currently in this mode and I don't want to convert to other modes since it brings other benefits. Thx a lot.

A remark for potential implementation: by definition, if target-folder: is not included, the sorting specification applies to the folder in which the note lives. That means, there could be an expectation for the sorting spec contained in the folder note in mode Outside Folder, with Same Name to apply it not to the enclosing folder but to the relevant subfolder.

I don't have an idea how to approach this in a non-confusing way. The implementation should probably follow standard rules and not make any exception and thus become not-so-convenient in this particular scenario. Typically putting sorting spec in 'folder note' frees you from specifying target-folder: thus making the sort spec more concise.
