Implement Suggestions API

[andregasser]

Mastodon's Suggestion API provides endpoints to retrieve server-generated suggestions on who to follow, based on previous positive interactions. The goal of this task is to implement the following endpoints of this API in BigBone:

• View follow suggestions (v2)
• Remove a suggestion

The Suggestions API as it is documented by Mastodon can be found here:
https://docs.joinmastodon.org/methods/suggestions/

Tip: A lot of other endpoints similar to this have already been implemented. In order to get an idea how to implement this, I suggest that you study the code upfront. Start with one of the *Methods.kt files.
