Endpoint need to be updated according to Gorse v0.5.x changes

Hi,

Following api endpoints need to be updated according to recommender changes in latest Gorse version:

- getItemNeighbors() -> item-to-item recommendation with name parameter
- getUserNeighbors() -> user-to-user recommendation with name parameter
- Need a new api for non-personalized recommendation with name parameter
- getSessionRecommend() ??

Thanks & Regards,
Gkf

Start by locating getItemNeighbors(), getUserNeighbors(), and getSessionRecommend() in the TypeScript SDK and compare their endpoints with the Gorse v0.5.x API changes. Confirm the required name parameters and the non-personalized recommendation endpoint; done means the affected SDK methods and new API match those changes.
