Duplicate components generated

[braco]

If we have a spec like this:

components:
  schemas:
    FooBar:
      $ref: "schemas/Foo/Bar.yml"

this package will generate duplicate schemas: FooBar and Bar. It seems like the correct behavior would be deferring to the chosen name FooBar and not creating Bar, especially since you're dropping folder structure.

Excellent start to this package by the way! I tried about 20 different OAPI generating frameworks today.
