Custom templates with custom conditionals can generate annotations

[matteh11]

Hi, we use your tool frequently and like it very much.

I have a feature request. We need to be able to generate annotations in the code based on custom vendor extensions in the schema on certain field.
e.g by adding a certain attribute x-custom-attribute to a certain field, I would like to in the mustasche template have a conditional that if set, generates an annotation in the resulting kotlin code.

We are using your gradle plugin and in it I see no option to specifiy custom templates.

Please see this for reference
