* Somewhat tighten error handling why: Zombie state is invoked when the current peer turns out to be useless for further communication. While there is a chance to further talk to a peer about another topic (aka healing) after some protocol failure, it makes no sense to do so after a network problem. The latter state is explained bu the `peerDegraded` flag that goes together with the `zombie` state flag. A degraded peer is dropped immediately. * Remove `--sync-mode=snapCtx` option, always start snap in recovery mode why: No need for a snap sync option without recovery mode, can be achieved by deleting the database. * Code cosmetics, typos, prettify logging, debugging helper, etc. * Split off snap sync sub-mode handler into separate modules details: The original `worker.nim` source has become a multiplexer for several snap sync sub-modes `full` and `snap`. The source modules of the incarnations of a particular sync sub-mode are places into the `worker/play` directory. * Update ticker for snap and full sync logging
