feature request: auto-refresh preview on cursor move

Describe the feature

I'd love to have a mode where the preview refreshes automatically on CursorMove (including refreshing/staying active, after cd'ing to new dir)

A non-working autocmd-based solution that I've tried but then realized that this won't work since autocmds don't have a ft property so not sure how to get it to restrict to the oil window

      vim.api.nvim_create_user_command("OilPreviewEnable", function()
        require("oil").select({ preview = true }) -- preview current right away
        vim.api.nvim_create_autocmd({ "CursorMoved" }, {
          ft = "oil",
          callback = function()
            require("oil").select({ preview = true })
          end,
        })
      end, { nargs = "*", desc = "Enalbe Oil Preview Mode " })
    end,

But I hope this conveys the idea. In MacOS finder you can ctrl-space to start a preview and c-n, c-p, and then ESC to stop preview - would be cool to be able to do the same here via oil specific <esc> and <c-space> mappings for turning on/off the live preview

Provide background

Very similar in spirit to #41 - trying to improve speed at which I can explore novel repos

This is not exactly the answer, but you could take a look at (and build upon) https://github.com/stevearc/oil.nvim/discussions/39 to at least get closer.

I added this as the default behavior. If anyone finds the auto-update behavior intrusive, put in a request and I'll add a config option to disable it.

Just for your education, the way you could do this yourself is by creating a FileType autocmd that runs on oil buffers, and then inside of that create a buffer-local CursorMoved autocmd.

This is amazing, just made my day. Such a great convenience.

Also really appreciate the explanation, really kind of you 🙏
