Enhancement: Ability to select multiple radio buttons

[TrueNorthTrent]

Love the plugin, use it on a few different projects. I've ran into a corner case where it would be cool to be able to have multiple radio inputs selected per row -- instead of the one-per-row nature.

I might work on adding that functionality at some point

@TrueNorthTrent hello, thank you very much! 🤗

I suppose in this case it would be not a radio grid, but the checkbox grid.

If you could add this type of field feel free to create a pull request.
