No way to reset user id about analytics-swift

@alanjcharles can you update the documentation he cited? It's a bit confusing.

Hi @nekto-zum you can reset a userId with the reset() method: https://github.com/segmentio/analytics-swift/blob/main/Sources/Segment/Analytics.swift#L166

I would actually argue that the reset() option you are proposing is a bit too nuclear for a general usage. Imagine you have login/logout events. I don't necessary want to reset everything, I want just to drop user id. Can more granular setting be added? As I mentioned in the referenced code it is actually supported to pass nil...

While I can understand your point of view, the intent here is to preserve privacy of the user(s). By resetting the anonymousId/user/etc via reset() there's nothing to link it back to a previous session. Our other libraries work this way and previous libs have worked this way for quite some time. So calling reset() is the recommended path for what you're attempting to do.
