'Response' suffix causes duplicated structs #386

I have some endpoints in my spec like this one:

  /v1/auth/phone/login:
    post:
      summary: 用手机登陆/注册
      tags:
        - Auth
      operationId: LoginByPhone
      requestBody:
        required: true
        content:
          application/json:
            schema:
              $ref: '#/components/schemas/LoginWithPhoneRequest'
      responses:
        "200":
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/LoginWithPhoneResponse'

If I generate server code it is ok, but when I generate client code oapi-codegen creates structs with Response suffix which causes deduplication of my structs.

Maybe it would be better to make this suffix configurable or change it and other suffix/prefix literals to with _ at the beginning so it would be OperationName_Response?

Initially I wanted to use a custom template, but this suffix is generated by the function.
