There are a bunch of places in genqlient where we just kind of hope you don't have ridiculous casing conflicts in your schema. Apparently with enum values there are actual schemas that have this problem! Now we have an option to disable. I ended up putting it all under `casing` instead of in `bindings` so we can clearly document the list of algorithms we support, and so we can have an `all_enums` value if you're working with a schema with a lot of this; in the future we may want to add similar behavior for types/fields, add more possible algorithms (e.g. to make things unexported), etc. I added tests for the new feature, although the way the tests are set up it wasn't convenient to do so for a schema where this is actually required. I also added a check for case conflicts that points you to this option. (I don't want to do it automatically for reasons described in the issue; mainly it just seemed a bit too magical.) Fixes #265.
