Vue 2.7 compatibility

[JorisAerts]

Currently, the plugin does not work with Vue 2.7.
I get an error saying: Module not found: Error: Can't resolve '@vue/composition-api' in '[filename]'

I've merged the corresponding PR but I'm still not sure about how to expose the new option in the preset 🤔

I like your suggestion "target: 2.7", but it would imply somewhat that multiple choices are available, while 2.7 is the only version 2 ever which will support an internal composition api.

I suggested compositionAPI: "native" or compositionAPI: "module", or something like that.
Or "embedded" iso "native" would also work.

Or something like:
{ compositionApi: true } // 2.7
and
{ compositionApi: { module: false } } // 2.7
{ compositionApi: { module: true } } // < 2.7

Fixed in https://github.com/vuejs/jsx-vue2/releases/tag/v1.3.0

I didn't choose the module option because it's a little bit confusing in the context of JavaScript (module often refers to the module system, i.e. CJS or ESM).

Thanks for your suggestions anyway!

Is this fixed? I'm using v1.3.1 but I'm still facing this issue that the dependency @vue/composition-api was not found.
