Add support for parameters with `collectionFormat: csv`

[reusst]

Hi,

this works:

      parameters:
        - name: id
          in: path
          description: ID of pet to use
          required: true
          type: array
          items:
            type: string
          collectionFormat: csv

-> repeated string id = 3;

Does not work:

      parameters:
        - $ref: "#/parameters/id"
...
parameters:
  id:
    in: path
    name: id
    description: ID of pet to use
    required: true
    type: array
    items:
      type: string
    collectionFormat: csv

->

array id = 1;
...
repeated int32 id = 1

Do you have any idea?

Howdy @reusst, sorry for the delayed response.

I believe the issue you're running into is the lack of support for the collectionFormat field at the moment.

I think it'd be a handy feature to have so I'm going to update this issue to reflect it.

I hope I can have time to add this soon, but PRs welcome!
