/**
* Name: Bluesky Connector
* Description: Post to Bluesky, import timelines and feeds
* Version: 1.1
* Author: Michael Vogel <https://pirati.ca/profile/heluecht>
*
* @todo
* Currently technical issues in the core:
* - Outgoing mentions
*
* At some point in time:
* - post videos
* - direct messages
* - Sending Quote shares https://atproto.com/lexicons/app-bsky-embed#appbskyembedrecord and https://atproto.com/lexicons/app-bsky-embed#appbskyembedrecordwithmedia
*
* Possibly not possible:
* - only fetch new posts
*
* Currently not possible, due to limitations in Friendica
* - mute contacts https://atproto.com/lexicons/app-bsky-graph#appbskygraphmuteactor
* - unmute contacts https://atproto.com/lexicons/app-bsky-graph#appbskygraphunmuteactor
*
* Possibly interesting:
* - https://atproto.com/lexicons/com-atproto-label#comatprotolabelsubscribelabels
