Collaborative filtering api method is missing in library

In Gorse, there is an option for intermediate recommendation:

_Collaborative Filtering Recommender
Recommenders based on similar items and similar users require that the recommended items need to be linked with similar users or historical items of the recommended user, which limits the scope of recommended items searching._

This api is called through:
{{url}}:8088/api/intermediate/recommend/$User
{{url}}:8088/api/intermediate/recommend/$User/$Category

Could you please apply this recommendation method to gorse-js lib?

Thanks,

Start in the gorse-js library's existing recommendation API methods and compare their request and path-building patterns with the two intermediate recommendation endpoints in the issue. Done means the TypeScript client exposes both user-only and user-plus-category forms and they call the corresponding endpoints; no specific files or tests are named.
