Inject the request method into service classes

Rather than import the request method directly, service classes will now
receive it as a constructor argument and save it as a private field. This
makes the constructor classes more generic and testable.

To avoid breaking changes, service class instances are instantiated and
exported from index.ts with PascalCase naming. This allows users to
update with no changes, because the public API does not change
noticeably.
