Add wildcardSet method to support setting path with wildcards

[randing89]

Added a new method to support path with wildcards. I didn't change the original set method because I don't want to introduce a new parameter. So user can choose to use wildcardSet when they can ensure their path does not actually contains * like {'*':'abc'}

Hey. Just want to know what's the plan for the plugin support?

it's in the 1.0 branch, it's actually 'ready', but the author doesn't want to rely on Typescript, so I need to find an alternative before the release
