Subject: [PATCH] feat(parser): export parser.Children (#327)

* feat(parser): export parser.Children

As parser was moved to internal/parser, it is not possible to import it into
external projects anymore.

However, parser.Children() is handy to use in static analysis tools, so it is
worth exporting. This does that by adding a stub package
`github.com/google/go-jsonnet/parser` that wraps the internal function.
