Support Bendy Butt & Gabby Grove feed formats
Gabby grove is an alternative feed format which we used to support. Support for it was disabled in #425 due to large changes in the way feed and message identifiers are formatted, but we could bring it back.
We should consider supporting bamboo instead / in addition? Gabby Grove has a bunch of nice features but i think only go-ssb supports it.
Just to clarify this is what the protocol documentation states:
Clients, for compatibility reasons, have a main classic feed alongside the root metafeed.
This implies that every client should have a classic feed as their main feed. What does this mean in the context of gabby grove or bamboo? I thought that those are only supposed to exist in the form of metafeeds.
This will be addressed in scuttlego and specs need to defined.
