Support PeerTube objects

[FurblandChannel]

PeerTube is a platform for sharing videos over the Fediverse, and as such has its own set of objects which extend ActivityPub. Most Fediverse platforms implement it. See below: https://docs.joinpeertube.org/api/activitypub

PeerTube is among the ActivityPub implementations that can randomly send an object instead of a string, an object instead of an array of objects and so on. This JS mindset of arbitrary types is very hard to work with from Go (I mean, without implementing a dynamic, reflection-heavy type system on top of the Go one) so I don't think this is an easy fix.
