#### Description

MR to add another xavp_copy function taking 4 params

```
 xavc_copy("source_name", "source_index", "destination_name", "destination_index")
```

This will let the user copy to a specific position in the stack (replacing its value).
This would bring coherent behaviour compared to assign to a specific index vs appending.

Example : swapping xavp in and existing stack:
(second and third elements)
```
$xavp(a=>x) = "a-0-x";
$xavp(a[0]=>y) = "a-0-y";
$xavp(a=>x) = "a-1-x";
$xavp(a[0]=>y) = "a-1-y";
$xavp(a=>x) = "a-2-x";
$xavp(a[0]=>y) = "a-2-y";

# INFO: <script>: NEW $xavp(a[0]) = [a-2-x][a-2-y]
# INFO: <script>: NEW $xavp(a[1]) = [a-1-x][a-1-y]
# INFO: <script>: NEW $xavp(a[2]) = [a-0-x][a-0-y]

xavp_copy("a", "1", "c");
xavp_copy("a", "2", "a", "1");
xavp_copy("c", "0", "a", "2");

# INFO: <script>: AFTER $xavp(a[0]) = [a-2-x][a-2-y]
# INFO: <script>: AFTER $xavp(a[1]) = [a-0-x][a-0-y]
# INFO: <script>: AFTER $xavp(a[2]) = [a-1-x][a-1-y]
```
