Support for `globstar` option

[benmccann]

netlify/build uses the globstar option. I wonder if that one would be hard to implement or there's a good workaround for it?

See netlify/build#6354 (comment) for more details

this should be as easy to implement as using the noglobstar picomatch option, unless i'm missing something tinyglobby handles on its own
