## Summary:
Previously, we actually allowed you to put several genqlient directives
on the same node, but the semantics were undocumented (and somewhat
confusing, when it comes to `typename`). In order to support directives
on input options, we're actually going to be encouraging this usage (see
notes in #14), so it's time to fix it. To avoid confusion, I just had
conflicting directives be an error, rather than defining which one
"wins". The same applies to specifying the same option several
times in one directive.
I also fixed two small bugs:
- `typename` on an operation would incorrectly cascade down to
all input types in a query (causing conflicts).
- directive parse errors had useless positions, now they're correct
