adjust timestamp functionality depends on org-link-edit.el and I did not know that, here's how I fixed it

When I tried to make it work the (GREAT!!!) functionality of org-media-note-adjust-timestamp-offset it failed because function (org-link-edit--link-data) [1] was not defined

Then I discovered that I just needed this piece of code [2] which I got it from here [3], and this is by the way the proper place according to [4], you might want to get all the package, but I just needed that two functions to make the "adjust timestamp" functionality to work

I am just reporting how I solved the problem, I don't know how this should be fixed, just updating README.md docs? code refactor? code inclusion?

[2] emacs lisp code:

(defun org-link-edit--on-link-p (&optional element)
  (org-element-lineage (or element (org-element-context)) '(link) t))

(defun org-link-edit--link-data ()
  "Return list with information about the link at point.
The list includes
- the position at the start of the link
- the position at the end of the link
- the link text
- the link description (nil when on a plain link)"
  (let ((el (org-element-context)))
    (unless (org-link-edit--on-link-p el)
      (user-error "Point is not on a link"))
    (save-excursion
      (goto-char (org-element-property :begin el))
      (cond
       ;; Use match-{beginning,end} because match-end is consistently
       ;; positioned after ]], while the :end property is positioned
       ;; at the next word on the line, if one is present.
       ((looking-at org-link-bracket-re)
        (list (match-beginning 0)
              (match-end 0)
              (save-match-data
                (org-link-unescape (match-string-no-properties 1)))
              (or (match-string-no-properties 2) "")))
       ((looking-at org-link-plain-re)
        (list (match-beginning 0)
              (match-end 0)
              (match-string-no-properties 0)
              nil))
       (t
        (error "What am I looking at?"))))))
