Issue: orderBy to accept array of strings instead
In the documents, it says:

`await Model.orderBy('-created_at', 'category_id')  `

is it possible to somehow pass an array of strings as the args?
Pull request description: feat(builder): accept array for `include`, `append` and `orderBy`
Accept array of strings for `include`, `append` and `orderBy`.

Closes #140
