Use with vue-cli

[jvbianchi]

In the readme, would be useful to put a Use with vue-cli section

PR welcome, the poi config https://github.com/egoist/lit-vue/blob/master/example/poi.config.js should work for vue-cli too I guess

A vue-cli plugin would also be nice

[vesper8]

any luck getting this to work with vue-cli @jvbianchi

unfortunately, I don't have any clue how to apply this poi.config.js to make lit load correctly under vue-cli
