Nested Abolish Alternatives

[ghost]

I would be good (at least: it would make more sense to me and be in the spirit of the plugin) if Abolish could use alternative braces nested within each other. This would be useful for multiple versions of version of a word. For example, at the moment I have to do this:

Abolish d{,s,st,nt} do{,es,es'nt,n't}

But it would make much more sense to me to do this:

Abolish d{,s{,t},nt} do{,es{,'nt},n't}

I too wanted such functionality, so I incorporated it in my first nvim plugin
