* rewrite Stream{} to use much less mutex locking, update related code
* use new context for the stream context
* ensure stream gets closed on return of writeTo / readFrom WSConn()
* ensure stream write timeout gets cancelled
* remove embedded context type from Stream{}, reformat log messages for consistency
* use c.Request.Context() for context passed into Stream().Open()
* only return 1 boolean, fix tests to expect multiple stream types in messages
* changes to ping logic
* further improved ping logic
* don't export unused function types, update message sending to only include relevant stream type
* ensure stream gets closed 🤦
* update to error log on failed json marshal (instead of panic)
* inverse websocket read error checking to _ignore_ expected close errors
* Add/update some DB functions.
* move async workers into subprocessor
* rename FromFederator -> FromFediAPI
* update home timeline check to include check for current status first before moving to parent status
* change streamMap to pointer to mollify linter
* update followtoas func signature
* fix merge
* remove errant debug log
* don't use separate errs.Combine() check to wrap errs
* wrap parts of workers functionality in sub-structs
* populate report using new db funcs
* embed federator (tiny bit tidier)
* flesh out error msg, add continue(!)
* fix other error messages to be more specific
* better, nicer
* give parseURI util function a bit more util
* missing headers
* use pointers for subprocessors
