[datatable] provide "swipeout-cell"

This is a (multiple allowed):

• enhancement

• Framework7 Version: 2

The datatable component (https://framework7.io/docs/data-table.html) has this:

<th class="checkbox-cell">
          <label class="checkbox">
            <input type="checkbox"/>
            <i class="icon-checkbox"></i>
          </label>
        </th>

to provide a "checkbox-cell".

Would be nice to even provide a "swipeout-cell" (https://framework7.io/docs/swipeout.html).

For example:

<th class="swipeout-cell">
<div class="swipeout-actions-right">
<a href="#" data-confirm="Are you sure you want to delete this item?" 
class="swipeout-delete">Delete</a>
 <a href="#" data-confirm="Are you sure you want to delete this item?" 
class="swipeout-delete">Edit</a>
..
</div>
</th>

So with this, many actions can be bundled within a swipeout-cell.

I think, the "swipeout-cell" should only be allowed at the first or at the last column (".swipeout-cell-left" and "".swipeout-cell-right"), but not in between, because it may disturb the scroling from left to right when having many columns. But you will see..

Start with the datatable and swipeout documentation linked in the issue to understand the existing component behavior. Define how a swipeout cell should work, including left or right placement and bundled actions, then determine the implementation and validation points from the datatable component.
