Feature: Update // @deno-types="..."

[Milly]

Feature request.
When using npm: packages, we may need to get types from @types/.... It would be nice to be able to update the package version in special comments like following:

// @deno-types="npm:@types/foo@1.2.3"
import { foo } from "npm:foo@1.3.9";

If this special comment is present, deno will write the package information into the deno.lock file just as if it were a package specified in a normal import statement.

I've been overlooked that. Thanks for pointing it out.
