Accepting data in toggle & wrap functions

[oyeanuj]

Hi folks, thank you as always for the plugin! I was wondering if the toggle and wrap functions should take an optional data to be able to pass in things like syntax (and thus allowing easier interoperability with slate-prism).

My personal usecase is Github style markdown of three ~~~/``` followed by the language name. Using regex, I can capture the syntax proposed but can't use the wrap or `toggle` functions to set the code block.

The other alternative would be to do an insertBlock but since the wrap & toggle seem to be exposed utilities, it felt 'safer' to use those.

Thoughts?
