+- New feature: the core can request the pathfinder service API instead of the `circles-api`. The pathfinder service is used by default. Methods affected: `core.token.transfer` and `core.token.findTransitiveTransfer`. New parameters for instantiating the core are needed: `pathfinderType` (`cli` or `server`, by defalut `server`) and `pathfinderServiceEndpoint`. Use `randomUUID()` for the pathfinder server requests ids [#165](https://github.com/CirclesUBI/circles-core/pull/165) [#169](https://github.com/CirclesUBI/circles-core/pull/169) [#175](https://github.com/CirclesUBI/circles-core/pull/175)
