Add the feature to change tags names of section and column

[Askar Mukhametshin]

Thanks to the Elementor Canvas template, you can now create page without the theme's header and footer. Now there is a need for semantic tags. To do this, please add the tag name setting for section and column

In detail:

1. Sections: div, section, header, footer
2. Columns: div, aside

Thanks for the idea! we want to add this feature in the next version of the plugin.
