Org-mode ASCII Export to support numbered references for links

[Husain Alshehhi]

Org-mode's ascii export uses the link's description to create a reference to it 
at the end of the document. For example, a link to google will look like this:

,----
| This is a [link to google].
|
| [link to google] <https://www.google.com>
`----

Is there a way to modify this behavior to using a number reference rather than 
link description? Such as:

,----
|
| This is a link to google[1].
|
| [1] <https://www.google.com>
`----

The reasoning behind this is that using numbers is more intuitive (as it is the 
common practice it plain text posts, emails etc.) Also, when there are two 
different links with the same description, the export is going to be confusing 
to the reader. This happens when I use the description "link".
