Use core columns block

hey!

I like that the plugin uses CSS Grid to create the columns.

Would prefer that the plugin uses the classes and markup like the core Gutenberg block for columns. That way the user needs to download less CSS.
Not sure how hard it is to use the “real” core block. But at least recreating the markup structure and classes would be nice.

Also the styles by the theme or core would be used, making a more uniform frontend layout. No need for manual fine tuning the styling of the block by website owners.
